I have been reloading .308 for about 12 years now. But not until recently did I get real "serious" about it. To the point of seperating brass by brand AND weight. I recently "discovered" (probably been happening all along but I didnt pay much attention to it) a difference in the way my model 88 Winchester recoils. Basicly two very distinct differences. With most of my loads a "sharp" snap or popping up off of the sandbag is present. In less of my loads a distintly different "punch" backward with no "bounce" of the barrel. Accuracy doesnt seem to vary much. As I have a few loads in 150, 165 and 180 grain that can consistantly punch MOA holes at 100yds. And the one load that had the smoothest "punch" recoil was a 180 grn load. Five shot group 1.125 MOA. Just curious if anyone can help me understand the reason why the gun would recoil so differently. And what that would mean. Thanks, and a great site here on all things shooting long range.
