[QUOTE="Dgutter, post: 492902, member: 32130"] Richard, I'm definitely not trying to argue. I'm just looking for the extra pieces to the puzzle that I'm missing. I do understand your point about the case being pushed back as the bullet "stands still". However, what I'm thinking is that the pressure in the case acts on all inside surfaces equally including the bullet. With light neck tension as most reloaders use the bullet would (imo) have to release from the case. Now at this point i suppose the "back pressure" created by the bullets mass vs case mass could be the driving force that pushes the case against the bolt face. But even then the bullet wouldn't be in perfect alignment with the bore as it "released" from the neck tension before hand. Idk??? I could be wrong as well and in my attempt to explain my thought process I was hoping to be proven wrong (or right) through yourself or many of the other knowledgable folks here. Maybe I should crunch the numbers myself...but that just takes so much time. :D [/QUOTE]
