[QUOTE="Brent, post: 8636, member: 99"] GoneHuntin, Even with the same charge weight used, PSI at the muzzle on the shorter tube would be higher, add more powder to equal the MV's out just makes that worse, as you probably have already figured. Enter/return key posted before I was done. [img]images/icons/rolleyes.gif[/img] Switching to a faster powder might be a better choice than simply adjusting charge weight. I've seen bullets do better at long range than they do at shorter, but it could be that one concentrates harder and does better at farther distance, maybe unconsciencely. Could be low sample size makes it appear they tighten up. I'm not sure, but I have seen it. I've got a way to determine if the "same" group at 100 yards gets tighter at much farther distance and still plan to run some tests to end this question in my mind. If it does prove to be true, you'll still be hard pressed to nail down the cause for it. I think the heavier the muzzle is, the less it may climb upon recoil, and probably is more consistant from shot to shot. If a bullet yaws back and forth steadily until it slowely dampens out from disruptions at the muzzle, I don't see why it couldn't change direction each time it yaws the other way from the decreased drag on one side, isn't this exactly what happens when they start to keyhole at LR, groups open up wildly?
