I agree completely. Some are fast, and some are slow. I have a 7x57 that shoots more like a 280REM. It puts a 150gr bullet out the muzzle at 2850fps and that is with a middle of the road powder charge. If you are wondering, it is about 200+ fps faster than what the books show I should get.dog gone said:Allot of it has to do with the barrel. I have shot two rifles same caliber, bullet, powder, etc everything the same except barrel legnth. One was 24 inches long and one was 26 inches long and the shorter of the two the velocity was faster.
I don't think that really is right. There may be rifles with 22" barrels that shoot better than rifles with 24" barrels, but you don't see competition shooters out there shortening their barrels for more accuracy. Most competition shooters out there are going with much longer barrels than anyone would care to try and hunt with to help improve accuracy and stabilize bullets better. Some of them shoot from 40" barrels or even longer.Bernie P. said:One thing to consider is that shorter barrels tend to be more accurate so for long shots you might well be better off with the 22" anyway.
