I've been using Winchester 230-grain hollowpoints in my S&W 1911 for a couple of years. It's my duty load (security work). Lately, I've noticed something odd - perhaps alarming? When I go to work, I chamber a round and carry cocked and locked. After the shift, I unload the weapon, and re-insert the previously chambered round into the magazine. This results in numerous chamberings of the same cartridge. I noticed that there is a difference in the overall length of the cartridge from the others - the bullet seems to have seated lower than the other cartridges. There is a distinct mark on the brass revealing the outline of the bullet's base. If this is due to the repeated chamberings, am I risking a high-pressure load, since the bullet appears compressed? Is this an ammo issue or is there something about the Smith and Wesson 1911 that batters the head of the cartridge and hammers the bullet downward? This isn't happening with just one box of Winchester 230-grain hollowpoints. I'm wondering if Winchester needs to secure the bullet better?
