Yes, platform matters very much.
In a semi-auto platform the brass has a greater opportunity to stretch and deform from things like generous chambers and the violent extraction.
In a manual action like a bolt, break, or falling block the brass has more support through the firing process. I know folks who get around seven reloads out of FGMM brass through their bolt guns, but I don't know anyone who gets that number out of gas guns.
Machine guns are awesome until you have to carry one.
