horsefly,

  I know many shooters can shoot all day with no fouling problems ,or flyers. See my comments tho on gorup size and flyers.

  I suppose I should make my reference a little clearer on my loss of accuracy. I thought you might get it when I mentioned what happened with one load and with my "accuracy" load for that gun.

  Here's the story..... The NCOWS Buffalo Match is a 4 day, 25 shots a day match at Buffalo Shilouettes of three sizes set at unknown distances out to around 300 yds. There is a time limit of ten minutes for each 25 shots, and in case of a "kill" tie, time determines the winner. So, times for those 25 shots, of the better shooters, would run in the 6 minute area. I usually ran it in 5 1/2 to 6 1/2 minutes. In this time frame you would have to move your sticks once or twice as the course was set up in at least a 180 degree arc. When you got done you couldn't hang onto the gun by the barrel.

  So a load had to be developed  that would fire those 25 shots in that amount of time with a reasonable amount of accuracy. Under 2 MOA. It ended up that the best load for this match was not my accuracy load. The testing I did for this load is the only one I put thru what I mentioned above. Now the latest testing I'm doing with my .40/65 shows that I can go at least...... as many as I've tested so far...... 20 rds. and not lose accuracy over what I get with 5 shots. BUT! This is also using a blow tube, or blow tube/dry patch method.

  When wiping between shots for Schuetzen shooting with my .32/40 or .38/55, I find that I can shoot all day with no loss of accuracy. BUT! Again. I had to develop a load that eliminated the flyers that seem to crop up. To do this I've dropped one lube groove from my bullets. This of course doesn't get rid of ALL the flyers, but I might only have one or two during up to 100 rds. in a days shooting.

  Again, as mentioned in my last response. You have to take into account the accuracy requirements and what would be considered a flyer. In the NCOWS load I could have had flyers and not even known it. Might have been one of those 96 or 98 x 100's I missed was a flyer! But for Schuetzen shooting where the accuracy is such that one shot in ten that makes a 1/2" group a 3/4" would be considered a flyer. Same thing with Shilouettes. Say, for example, a load on the Rams that normally shoots into 1 MOA at that range, and you get some shots that make the group 2 MOA. No big deal as it would be a knockdown anyway if the center of the group is centered up on the Shilouette. You might even get away with a shot that made the group 3 MOA.

  When talking flyers we always have to consider the venue being shot. My mistake for not making this clearer.

feather,

  I'm not saying whether a soft, or hard bullet would be best for Shilouette. I just don't know.

  You bringing up that you think a bullet uses momentum rather than energy to knock down a Shilouette is interesting. I don't think I've seen that point suggested. Mostly it's suggested that dwell time on the target, and the energy that can be transferred in that amount of time dictates which is better. AND... there seems to be good arguments for both sides.

  The soft bullet side seems to be that more energy is transferred since it will stay on the target longer as it flattens out. The hard bullet advocates suggest that since no energy is wasted compressing the bullet there is more energy transferred to the target.

  The more I think on this the more confused I get as I can see merit in both sides. So, might just be a case of what works best in your gun, and it's a 50/50 toss-up as to which is better.

  On Pioneers and accuracy.

  It's not mentioned a whole lot but the Buffalo hunters did wipe their bores out after so many shots. Never have seen what would be an average but it appears all carried a wiping stick and canteen for the job. It purported that when they ran out of  that water they used a natural source.  Grin Since most of the prime robes were taken during the Winter they would also put their rifles into a snow bank if it got to hot. It was thought, at the time, that a gun that got to hot lost it's accuracy. Possibly cooling the barrel down drew in enuf moisture to make a succeeding shot clean the hard fouling out.

  On the accuracy issue..... I don't know where they got their figures but one source said that it took an average of 4 + shots for each Buffalo killed. So much for the deadeye Buffalo hunters!

bluesteel45,

You're right.  This thread did wander some from your original question.

When I was shooting paper patch bullets at silhouettes with a 45-70 Browning, I had very good success at the chickens and pigs with a 425 grain bullet.  The bullet had straight sides and a truncated cone nose.  It was also shot in a rifle having a 1 in 22 twist.  The point I want to make is that the bullet had a lot of bearing surface and very little nose.

I would recommend the Lyman #457193 which is a 405 grain bullet having a long body and short nose.  Lyman moulds are not that expensive and it could be a good start.  RCBS also make a 405 grain mould with one more grease groove than the Lyman.  That's a little less bearing surface but it might work as well.

In my 1 in 18 twist 45-70, I had very good success with the Saeco #645 mould which cast a bullet weighing 485 grains when a 1 in 30 alloy was used.  If you think that 485 grains is a sufficient weight decrease from the 500 grain bullet you're using now, I'd recommend the Saeco.  If not, I'd try the Lyman.

There are two other considerations to keep in mind when you begin using different bullets for different animals.  One is picking the wrong bullet for the wrong animal from your cartridge box.  More than once, a shooter has picked up a chicken bullet or two and shot them at the rams only to scratch his head wondering what was wrong.  If you store your cartridges nose down in the ammo box, it can happen easier than you think.  The other point is shoot-offs.  If you get involved with them, make sure you have plenty of chicken ammo with you at a match.  I've also seen competitors forfiet a winning position because they didn't bring enough chicken loads along to the match.

I don't know if this gives you any more information than you already had, but it's the best that I can do.

Hi Pete,

I believe that energy from the bullet is transferred to the target.  The question is....Is that energy transferred only in a straight line?

If all the energy from the force of the bullet impacting is directed in a straight line then maximum energy would be transferred within the diameter of the bullet.  However, if the energy radiates outward as well as straght ahead at the point of impact, then the energy transferred toward toppling the animal becomes spread out over a much larger area.  Which do you think happens?

Good morning, Board;

Pete, agree completely with your comments about the venue being important in what load you use and how you see (or don't see) fliers.  We have had several "hunter's matches" here where you have a limited amount of time to shoot as many rounds as you want.  No warm up, no sight in and no spotter.  In the last match, I used water to cool the barrel between relays.

So far as using "natural sources", I suspect the availability of that source depended on how badly scared you were at the start of the fight!

I also suspect that the idea of using undersized bullets and having them slug up was so someone was able keep shooting instead of blowing or wiping.  Sometimes, keeping shooting is more important than having a really accurate load.  Good enough is good enough.

Bluesteel45, you are right about this thread morphing into something else.  With this many posts, you know it had to happen.  So let's talk about light weight bullets for chickens.

As I mentioned in my first post or two in this thread, I whole heartedly endorse the idea.  For a while, I used a lighter bullet for both chickens and pigs.

Like feather, I believe you need a lot of bearing surface on the light bullet.  I used a Mountain Molds bullet that weighs about 408 gr and has the same bearing surface as a SAECO 745.

So far as using the wrong load, I use a felt marker to mark the case head of different loads even if they're in different boxes.  A lot of times, I also write notes on the sides of the cases, too.  The marker comes off in ceramic medium and doesn't hurt a thing.

Y'all be good.

feather,

  What do I think happens?..... Here my lack of Physics(?) shows up as I don't know if energy spread out over a large area would be more effective than the energy transferred to a smaller point. My gut feeling would go with the softer bullet. But......

  You inadvertently brought up a point I didn't think of. We have forgotten that the trajectory coming in on the Turkeys and Rams, at least, isn't straight on. But it would be the same whether for a light or hard bullet. Possibly the hard bullet would "skid" off the target whereas the soft one might "grab" a bit better.

  Interesting! We need someone who knows about this stuff to chime in.

  I've thought about your comment not to get the cartridges mixed up and have already thought of Horsefly's way of doing it. Good point tho about bringing enuff ammo in case you get into a shootoff.

undersized bullets.

  Interesting comments. I've never used them since I feel just the difference between the land top and groove bottom would be enuf to affect accuracy with the collapse of the bullet.

  One of the irregulars on here has a barrel chambered as was mentioned. No throat. He's used it with bore sized PP bullets in Schuetzen shooting and hasn't gotten anything like decent enuf accuracy. From what I've seen he would be pushing his luck to even hit the Chickens with cross sticks.

  But, seems like you've got a method that works better than his.

Horsefly,

  Got the biggest laugh out of your reference to whether you might have enuf "natural" water at the beginning of a fight. Well taken!  Grin

Blue,

  Yes. You're right about havng wandered off the topic a bit. But, take into consideration what feather, horsefly, and I have been saying. Lube is important in your "lighter" bullet and going to a lighter bullet, which translates into a shorter bullet, means less of it, so that has to be a consideration in picking it out from a whole host of possibilities. Then there's alloy. Again a shorter/lighter bullet by it's nature doesn't have enuf length in it's shank and might be subject to nose collapse if not taken into consideration..... A point I'm going to have to try out myself.

  So, even tho we've gotten away from what is a good light wgt. "Chicken" bullet, we have given you a whole bunch of ideas, and the thinking that goes with it, to help you make the right choice. A particular bullet we might recommend might not work in your rifle but the thinking behind our recommendations will at least keep you from making poor choices.

Interesting about soft or hard bullets; 1:20 or 1:30 are really not very different.  If Sharps used 1:16 for PP bullets, then maybe even 1:16 is still "soft".  I'm begining to think that maybe better accuracy with a given "alloy" is more a function of how the bullet fits the chamber e.g. engraving the rifling or touching the rifling, etc...  Possiblly a particular style of loading requires a different alloy.

About enegy delivered to a piece of steel, I am guessing [not an engineer] that the soft bullet could be delivering more "knock down" because the bullet deforming is not using up energy to deform, but instead is delivery all available energy or momentum.

I do not mind that the thread is wandering somewhat.  But I'm sure if a person is searching for a specific quick bit of info they will be frustrated by all the "other stuff".
Keep on hav'n fun!

Howdy folks.  This is my first post here.  I have been shooting BPCR at Ackley, Iowa for a couple of years.  I have been shooting rifle silhouette off and on since the mid 1970s, but have limited experience with the BPCR version.  The only reason I mention this is because, Iowa being geographically silhouette-deprived, I believe I am probably the only shooter in this area who has experience shooting on different full-size sillhouette ranges.  A couple of points about Ackley (and I won't mind being corrected if my facts are off a bit).  As noted, the BPCR silhouette events are still under development.  The range conditions, particularly the lighting and lack of dirt berms, make some of the targets very difficult to see.  I'm not saying this is necessarily a bad thing, but it may bother shooters who are very score and/or classification conscious.  IMO, it is a good thing that silhouette isn't a "groove" event where a perfect score is the goal.  BTW, the NRA classification system isn't used - all shooters compete equally. I am particularly conscious of the Ackley range because on occasion I shoot BPCR there on Saturday, then drive to Omaha to shoot HP silhouette with my son on Sunday.  The constrast between the ranges is significant, Omaha being a well-established range, and Ackley being more primitive - more like actual field shooting.  Target visibilty is much better at Omaha.  Another point is that the Cedar Valley Rangers, being an NCOWS affiliated group, period dress is expected, including the silhouette matches.  My observation is that they are not at all purists about total authenticity, but good manners dictate that shooters make a good faith effort to follow the spirit of the rules.  However, new shooters are always welcome, even if they aren't "dressed".  As previously discussed here, the non-NRA-type silhouettes like the buffalo shoots are a ball.  A couple of points of clarification.  I'm not sure that these are all NCOWS sanctioned matches, but may be just the local Cedar Valley Regulators.  Another point is that the buffalo matches are not herds of 25 shot over four days as Pete said, but typically are two herds a day for two days.

Pete, 
Sometimes you are just downright misleading.  I'm the "irregular" in question here, and what Pete neglects to mention is that this particular rifle also does not shoot any better (in fact it's worse) with any of three different groove diameter bullets from NEI, RCBS, and Hoch.  And that includes the last one being breech seated as well. Further, the accuracy issue is one that results over multiple shots.  First shots are quite accurate and indeed one such shot tore the pulmonary plumbing off a doe the other day.  Paper-patched, bore-diameter of course.

I wish you would, for one season, actually TRY bore diameter bullets instead of denigrating them constantly.  You rail against armchair ballisticians and shooters and how experience is everything, but by your own admission, you haven't shot bore diameter bullets and really don't have any experience with them at all.

Pete:  Re: post 110 where you mention possibly a harder bullet might "skid" off the target.  I'm not sure of this alloy thing, but I prefer a softer bullet for impact knock down and here I'm talking about the bigger heavier ram weight or buffalo targets.  Just seems to work better in real shooting at least for me.  For chicken size and weight targets I don't think it really makes any difference. The other thing I have found is that the bullet shape especially the nose shape and or alloy certainly seems to me to make a differance on the heavier targets..  I have tried the sharp pointed Lyman Schmitzer (sp) three grease groove pointed bullet around 485-500 gr thing.  This was a very accurate bullet and load out to about 300yds. I found that shooting at the buffalo I had any number of what appeared good hits, but the bullet skipped or actually "skidded" off the target, simply ringing it and not knocking it down.  I lay this to the angle that the bullet hit the target and the sharp pointed nose shape of the bullet. The sharp pointed nose of the bullet skidded off without imparting near as much energy on to the target.  This may have been  exasperated more do to the fact that the buffalo targets do not all set at direct square angles to the shooter and thus the bullet strikes the target and deflects in one direction or another. And again the trajectory angle of the bullet probally also adds to this mess.  Bottom line here is though that the sharp pointed bullets regardless of alloy, have a much greater potential to vere off and do not impart the energy needed.   Best regards steve witt

Steve,

Considering your success in winning matches, I tend to perk up my ears when you say something.  If I understand what you're saying here, it's that the formula for knocking down the heavier silhouettes is a bullet that is some combination of heavy,soft, and blunt.  Right?

Hi Paul:  I'm not sure its quite as easy as heavy, soft, and blunt, but in essence yes. Here is what I like, and its just a personnal "what works for me".  Its all pretty subjective and open to way to much debate.  For me this works fairly well, its not for everybody, and I'm not interested in converting anybody over. I'd be glad to help anyone, and I'm always interested in learning.  Right now I'm mostly intersted in the aspects of lube, for all this, and I must admit I'm somewhat perplexed by it.  But onward::: From .38 to .50 calibur, I prefer the .45, either 45-70 or 45-90, with the 45-90 by far the best overall.  Hopefully without sounding like a gamer, I simply think the 45-90 gives me the best knock down odds, and works the best for Creedmoor distances. In a nut shell: I prefer the .45 calibur, but If I were shooting a .38 or .40, (.50's are a little much for me) I'd stick to the same formula. I use the most "accurate" 1 1/2 MOA load I can develope with the heaviest, softest, Creedmoor style nose, bullet travelling at the highest velocity possible. The key here is putting it together to maintain the consistant "accuracy" level you need, can shoot to (at least some of the time) and want. And I might add that "accuracy" out of the gun has a lot to do with the various fowling control methods you choose.  I use a varity of methods, depending on the type match.  For instance I usually blow on silhouette, brush often on Buffalo, and may very well patch the bore on Creedmoor.  Its more of a how much time do I have to do the fowling control in a particular match under what are the given conditions for the day.    I use this for Buffalo, Silhouette, mid-range and Creedmoor.  At the beginning of the season, I pick one rifle, and usually shoot it exclusively for the season.  I don't change rifles, caliburs, or loads very often.   This is not to say loads can not be tailored for various purposes, I just don't have much need to do it, and the more I shoot the same gun the better I get the feel of it..   At the chicken line or at the little knock down targets (little buffalo) 200M or less, I don't think anything but an "accurate" load is needed. The leep of faith here is that the shooter can and does do his part.  That asside. hit them with about anything legal to shoot and they most likly will go.   Now its somewhat of a horse of another color at the Rams or the large heavy Buffalo.  I'm talking knockdown here. Again you still need that "accurate" load that shoots consistantly well in your rifle and be able to do your part.  Setting aside wind doping, spotting etc, I certainly believe big, (as in .45) heavy, fast, and soft, bullets are most important for knock down. Blunt bullets well, yes ,but I prefer a rounded Postell , or Creedmoor style nose.  Blunt for hunting yep, and they probally work about as well at distance, but, for me the rounded style I think is a little more accurate.  I'd add in I like the bullet travelling as fast as possible, and still maintain the accuracy.  I'm not saying you don't get more wind deflection with a faster bullet, but I think its a trade off and I think you get less vertical dispersion with faster, plus better bullet knock down momentum.  Heavier bullets have more momentum and I believe they off set the wind defelection of moving the bullet faster some.  Looking forward to next season.   Best regards steve witt

In order to keep the discussion regarding knocking down the animals from becoming confusing, I want to make it perfectly clear that energy and momentum are not the same thing.  According to Robert Rinker's book Understanding Firearm Ballistics, he states on page 340:

"The lethal effect, or killing power, of a bullet is closely associated with kinetic energy.  The knockdown, or shove of a bullet at impact is related to momentum. It is easy to confuse and mix-up the two, but they are like vinegar and oil in a dressing.  They are associated together and may even help each other, but they are still entirely different things."

Brent - The Irregular, welcome to the discussion.  As you already know, my only foray into bore size bullets was a dismal failure.  I suspect that chamber design may have had something to do with it but since I have no desire to go back there, I'll probably never know.

At least you went - I have had good success in my .45.  But the .38 won't shoot anything - bore, groove or any other diameter.  At least not for more than about 4 shots.

Mike T,

  Like you I'm not an engineer so what I'm telling here is just what I read on the other Forums. I think you're mostly right that soft bullets impart more energy to the target. But the hard bullet advocates say that energy is lost flattening the bullet out. More so than with a hard bullet and thus impart more energy/momentum, or whatever you want to call it to the Shilouette. Until someone with an engineering degree on this pipes up I guess you can take your pick as to which is best. Exponents of each seem to do pretty well.  Grin

  My only experience with knocking down Shilouettes was at the NCOWS Buffalo Match where they set the Shilouette's in the dirt. I found that a full house BP 525 gr. .45/70 load was just barely enuf to knock them down at ranges extending to about 300 yds. Next year I went over to a 600 gr. .50/90 and had no problems after that.

Jubilado,

  Hey Paul. How you doing?

  I can't say whether the current Buffalo Match is a "regular" NCOWS match now or not. Haven't shot it for a few years. But, when I did it was a part of the regular Nationals and listed as a side match, as was the 100 to 500 yd. match, which were the only ones I shot.

Brent,

  Well... What can I say. I was just making a point, and I'm sorry I left out the 1500 other words that would have been necessary to completely bring everyone up to date on the trials and tribulations of that particular gun.

  My point was... you couldn't get good accuracy with PP bullets. GG bullets weren't the thrust of my remarks. If they were I would have mentioned your lack of success with GG bullets in that gun to. But then I haven't ever seen you get target quality accuracy with any gun with PP bullets.

  PP bullets...... Now I know you're the PP guru of the Internet, but you also know for a fact, that I've shot literally thousands of PP bullets myself, and in my experience, MY EXPERIENCE, they did not then, will not now, and won't in the future, shoot as well as GG bullets. And I don't care if they're groove or bore sized. You also know I've wished you well, and encouraged you, in your search for target quality accuracy with them. Instead of getting on me you should be asking feather how he went about being competitive with them in Shilouette shooting. Maybe then we'll all learn something.

PETE
