[QUOTE="Canadian Bushman, post: 918478, member: 41122"] After showing up to this party late and reading this entire thread this stands out to me most. Whether the primer or the firing pin is putting/holding the case there, the shoulder of the case /chamber and the bolt face/firing pin are aligning the round when the bullet is leaving the neck. In my mind the similarity between the shoulder angle of the chamber and the shoulder angle of the case would play a very crucial part in the alignment of the bullets axis to the barrel's at this moment in the firing of the case. Two more things that grab my attention, most inherently accurate rounds used by picky shooters use aprx 30 deg shoulders and often ream their dies with the finishing reamer of their guns chamber. Two aspects i think could contribute to a cartridge/rifles's accuracy in regard to this point of bullet barrel alignment. [/QUOTE]
