Thanks! You got me to look at the action again and I learned some more.
The bolt face isn’t the issue with bulged cases. A barrel with too big a cutout for feeding might though. It’s often called an “unsupported chamber.” Some Glock calibers were notorious for tossing out cases with a “smile” shaped crease near the case head. If there were enough chamber pressure to bulge the case head - the only part that contacts the bolt face - you’d have much bigger and more exciting problems.
What I found that fascinates me is the LC 45 has a fixed ejector like a Mauser, 1903 Springfield, or almost any semiauto pistol. Not a plunger style ejector like an AR-15, Remington 700, etc.
