JD,

  Found the thread on BPCR about set triggers interesting to. Guess I'm a believer in them for both bench and offhand, even tho the argument against them seems to revolve around their increased lock time due to the lag time it takes for all the parts to move.

  I agree that one or two samples of any load are not really indicative of much of anything. When developing a load I will run the same load over several different sessions in order to build up a confidence level for it until I'm satisfied I have what I want. Every load gets at least two chances to prove to me that it acceptable. I don't keep chasing a load if it can't show me in two groups that it will perform. As they say.... The definition of insanity is doing the same thing over and over expecting different results.  Those that are good will be kept in the test procedure over a period of days and used as base lines to test others against. Sometimes these base loads will be replaced by another. No load I take to a match will have less than about 10 different trials at the range, either in tests or practice. That's what I was doing today. Both 1-25 and 1-30 have shown that with 14.2 grs. of 4227 they will both shoot pretty good, so I'll keep shooting them till I can determine a winner.

  Had to laugh at your comment about chasing the previous shot around. We've got a few of them at the local club to. Even when I KNOW, after a coupla rounds, that I need to move my sights I will only move them half the distance. I've been caught out to lunch to often not to.

PETE

I can't shoot this well, few folks that I've seen can.
I'd be delighted. 
But...
If making marginal changes in alloy, charge, size etc. don't make substantial and visible changes in group size, then probably/maybe they are making no difference. 
If we can't make a decision based on the available data, then maybe/probably there's no decision to be made.
In this case, I would suggest changing something major, like the bullet or the powder. I can't think what else is major in the system.
I changed from 14.5/IMR4227 to 12/AA#9 in my 30/30 Martini bench gun, because I read reports in the Journal/News that others were using the powder with good results. 
It made a substantial difference, quick. Averages of five 5 shot 100 yard groups went from around 1" to around 3/4", and the odd flyers were reduced.
I just got a M54 Win. in 30/30, with about a 9/16" dia muzzle and a 37# (est.) trigger pull. With my 30/30 load of 12/AA#9, 2 1/2, 311299 Alox (and a GC for no particular reason, don't use em in the Martini), this gun shot 5 in 1.1", .625" and 1.225". The powder works for me. 
I think I've read that AA#9 and H108 are about the same, and very like WW296/H110. 
Another suggestion is that you measure groups with a plastic clear ruler graduated in 1/10". This was suggested to me by John Alexander, and I find that it is easy to measure groups in .025" increments- the difference between say .900", .925", .950" and 1.000" is easy to see-and I'm old and trifocular.
Perhaps a more precise measurement wouls show differences in group size more clearly.
For me, if I can average 3/4" over the long haul, that's all I'll ever want or need from a SS gun. Bench matches can be won with the smaller groups making up the average.
Maybe AA#9 would work for you.

Pete;
I'll be interested in your grease-grooveless 22 bullets. I've got no-grease-groove molds in 30, 32 and 45, the 30 and 45 cut by Werner Wolf. They shoot fine with no leading, the 45 is the one I use the most, it's quite accurate out to 600 yards.
I wrote these up for the ASSRA News years ago, chrono measurements at zero and 200 yards showed BC's of the 45 bullet higher than I could believe. The whole point was to see if lack of grease grooves increased BC and reduced wind drift.
Good luck;

I'm just about to give up on a Savage 12 BVSS in 223 and Eagan 65gr and NEI 80 GR bullets. I can shoot averages about 1 1/4"-slightly better with the Eagan, slightly worse with the NEI. I've fored over 3000 lead bullets, can't make it go. I've shot 2 sets of 15 Sierra 52 gr hpbtm averaging .6+ or so. 
I've used Darr and Liquid Alox on the NGG bullets. 
With the 45 (446 gr bullet)I've max. 
records of 1162fps (17 Unique), 1279fps (23.5/SR4759)-I settled on the Unique load. No leading, except with Black Powder-which leaded FIERCE. Only 3/8" of COW over the Black stopped the leading. 
In 30/30 14.5/IMR4227 or up to 12.5/AA#9 gave no leading The bullet weighs 208 gr or so.
In 300 Win Mag, 24/IMR4227 or 17/Unique didn't lead. I've got no velocity records on the .30 that I can find.
The .32 is not pretty, it looks like a tin can with a bump on the top. With (max.)14.5/IMR4227 in a 32/35 Maynard, it didn't/doesn't lead.  At 12.5/IMR4227, velocity was 1395fps avg.
I cast almost all bullets from WW.
I have no idea what the max velocity without leading is. BTW, John Alexander shot the smallest 100 yard 5 shot group at the CBA Nationals in 2003 with a .223, he can average in the .6's with his Savage/s.
Good luck;

Pete,

I've been following this subject for the past few days, I am very encouarged to hear of Mr. Alexanders results with the .223's accuracy. I beleive there is great potential in working with the subcalibers (under 30). I'm currently running very comprehensive ballistic tests with various bullets, powders at 100 and 200 yards, some of these tests have involved velocities in excess of 1700fs with the 32 calibers, no leading has been observed, however, smokeless powder fouling has been seen with some powder and primer combinations. I will have more to write when my summer tests are completed. As far as the subcalibers are concerned, I beleive any leading/powder fouling may be less of a problem than anticipated. I reluctantly refrain from making any concrete statement at this time so as to not lead anyone astray, interesting things are in the offing.

joe b,

I beleive the 30-32's popularity are as you state, mild recoil, much background loading experience and shooting. Very good accuracy and BC's are obtainable with the correct bullet designs, better than 50% less wind drift at 200 yds. The exciting thing to the lead bullet experimenter and the subcalibers  is the challenge of working with them to squeeze out the best accuracy. As a barrelmaker and moldmaker (25yrs ago) accuracy with the 28 caliber was equal to larger calibers if the shooter carefully read conditions. Shooter ability has eveything to do with the results where they count, at the target.
