Is movie editing pumping up the round count in some scenes?

Yeah, I hate that last one.
I know it's hard to reset scenes, but I think it would be worth it so you don't have a guy firing two shots with a jammed gun or something.

Course, it would be interesting if you just had your actors clear the jams in real time, would add a little pizzaz to firefights. But, do blanks jam a lot more than real bullets?
