I was preparing some Remington 7mm Express once-fired cases and noticed that a lot of the case mouths were bent in slightly, all the same amount and location. Is my assumption correct that these were fired in a Remington pump or semi and were bent as they were being ejected? Thanks

Maybe.
I use a 50 BMG round to make them round again.

To me, I think unlikely. However I would suspect hitting the ground post ejection the more likely culprit.

When the empty case leaves the chamber the spring loaded ejector pops the case into the receiver's more open section. The amount of dent is dependent on the power of the ejector and the geometry of the case. It happens on most Remingtons: BA, Auto, pump. Have seen body dents on .223 size cases. My latest 700 project is a 6x45 and all cases have dented mouths. They never touch the ground.

Could very well be that a pump action or a semi was responsible but just as likely someone that doesn't reload, throwing the bolt open like he was in a contest to see how far they would fly.
