[QUOTE="boomtube, post: 448166, member: 9215"] "But for factory sloppy SAAMI chambers loosely filled with SAAMI ammo, I can't imagine the front end of the bullet not improving the concentricity by jamming into the lands." That does seem intuitive but it's that sloppy fit that makes jamming SAAMI ammo in loose SAMMI chambers inconsistant. Just because we have centered the forward part of the exposed bullet into the bore doesn't do a thing for an out-of-line rear portion. That's why jamming tends to work pretty well (but not always) in tightly fitted BR chambers, the bullet is then aligned between two concentric points of contact. [/QUOTE]
