I wondered how many times it would take for an 'emergency release into battery' on my 1911 to change the overall length of a .45ACP round sliding up against the feedramp into the barrel. With a Winchester factory crimp, I just 'cycled' the gun 235 times (indexing the same round) before getting tired.
Before 1 cycle: OAL 1.272"
After 235 cycles, an irritated wife, and a tired hand: OAL 1.269"
I think the negligible difference is due to the copper jacket wearing off on my feedramp. I got a gun dirty, and didn't even fire it.
