[QUOTE="Bart B, post: 489759, member: 5302"] No response to my "floating" and "centering in the chamber shoulder" question, but here's another query anyway. As there's no such thing as a perfectly round case, chamber or sizing die, what do you mean by "concentric?" Perhaps to within a few ten-thousandths of an inch or so, which is typical. But that's enough to often cause interference between case and chamber walls when the case body diameters are not sized down enough.. And any interference there is will cause the barrel to whip a bit different for each shot. The end result is the bullet taking off in a slightly different direction upon its exit from the muzzle.
