Bob, for most PP is not the way to go Smiley.  As much as I like them from a traditional point of view, most of the time, the grease groove shooters come out on top.

How far are you from Richland? They shoot a lot of bptr at the Rattlesnake range.
Paper patch can shoot very well, but it takes a bit more attention to detail, especially fouling control, than when shooting greasers.

Chris.

The few that tried them here in the 90s gave up and went to GG.  We only had had one 10 shot match past 600, except for an occasional 1000 yard piggy back at KD-22 with high power shooters. 

From  what I have read here, PP really matter at the longest yardages improving the BC.

About 175 miles. I would love to do it again, but I can't shoot iron sights anymore.  Recoil is a migraine trigger too  Cry ;therefore,  I have shot primarily mouse guns for many years.

Schuetzenmeister,
George shot that score about a dozen or so years ago.
At that point it was at least a range record at Lodi.
Most BPTR long range matches since back then are now 10 shots for record at each distance. So, on a percentage basis,
his 141 would be about a 94 or so for a 10 shot string.
A 94/100 at 1K is likely to have been matched or beat since then. 
And re. the discussion, we are seeing more and more PP winners as people learn this aspect of BPCR. I am a convert
for the last 3-4 years. "Its not a "black art" Actually easy.
And of course there is the heritage of the old Creedmoor shooters and kind of a "cool factor" with PPB s.

That mouse gun shooting is a tough business.
One thing about recoil, the felt recoil from paper patch seems to be less than the greasers.

Are the reloads chronographed at Whittington to determine they are within the weight  - velocity numbers? I have standard 70gr powder & Postell 535gr gr rounds that are below the velocity numbers that I shoot to 1000yds?

Quote:
The NRA Black Powder Committee and NRAWC has changed the minimum requirements of bullet weight and velocity. There may be a 2% variance in bullet weight or velocity. Numbers in BOLD indicate the 2% variance. Only ammunition which produces these results, or better, and only rifles that have long-range sights will be permitted for use in the Creedmoor Championships. See the BPTR Nationals Ballistic Velocity Chart below for minimum requirements.

Yes. They would have you shoot 3 rounds over the chronograph, after they weighed your rifle/ rifles in.

beltfed/arnie  Good for George.  I always liked the 15 shot matches, especially if you were only shooting 3 distances a day.   

Ranch13  Mouse guns are tough and the targets are so close there is really no excuse for not shooting 250 in our Tacoma condition; no wind, no mirage  Lips Sealed

I have been thinking about dragging the 2.6 out and giving it a try since they started the 1000 yards up at Rattlesnake. I won't bore you with all the details but a migraine  nearly all day every day for 9 years makes one a little overly cautions of known triggers  Sad  There is nothing better than making 1000 yard bullseyes  Cheesy  Of boxes of medals and trophies, the 1000 yard bullseye patch from Ottawa Arms Collectors is a favorite.

There are some guys in Lodi who are having great success with patched bullets for sure.  And a few others here and there. 

I like them because that is the type of projectile used in the old matches, and they are quite easy to make shoot very well once you get the concept figured out.  I am selective with my desire to follow the old ways though.  I don't have any desire to go back to a 10 lb rifle, although a 3 lb trigger would work for me Smiley

Chris.

Schuetzenmiester you might want to get a hold of a can of the Olde Eynsford 1f powder, to try and tame the recoil of that 2.6 a bit. I've also rapidly became a fan of the limbsaver slip on recoil pads.
I had a good time the only time I shot the weinie gun match at Smithmoor,but it's still a 200 mile round trip to go shoot that, and as far as I know it's the only one with in a days drive. BPTR is my favored shooting venue, followed by 22 bpcr. 
The mysterious world of paper patch has come along ways since we started shooting the bpcr stuff back in the 70's, matter of fact it's come so far that we almost know now what most 10 year olds knew in 1879... Grin

They didn't the year before either. The general consensus is the majority of folks shooting the long range matches know enough about what they are doing that the velocity of a load is a mute point. And we've all got a dirt bath from a low shot coming in from "tested" loads.

Ha that's true.   I'd rather have a dirt bath though, than the wood splinter shower from hitting those 2x4's Smiley

Chris,  FWIW I was talking with Ernie Stallman one time at Lodi about the minimum requirements for BPTR loads.  He said those woodies you're talking about were one of the reasons for it.  He mentioned that a fellow was shooting a 40-60 of some sorts and instead of going through the 2X4 edgewise, it glanced off and hit the puller in the leg and hurt him pretty good. 
When I first started LR shooting at Harris, the butts were a little low and you had to sit under an overhang and rather than marking the targets, you would plot the mark and then report the score by radio to the line. Today, Harris has new butts and is much safer.  
For those of you that may have not scored for BPTR, the experience you have the first time a round goes through the 2X4 upright definitely gets your attention.  Cheesy
The newer scoring method certainly makes it safer for those marking at the top of the target and having a possible crossfire come in.  Bob

John Boy- I don't think they thought the math through very well when they came up with those rules.
