No don't call glock or at least don't give your serial number. Glocks rifling is a goofy polygon rifling, and for some reason will build pressure greatly with cast bullets. I have called them, they will tell you, not to ever shoot reloads. But Marlin will also not give you any reloading info in thier rifles either.

I shoot litterly 1000's of reloads thru my glocks. But they are all jacketed.

My advise is to resize the cases and take note of the web near the rim. If you see a bulge, back off your load a tad. If you continue to see the bulge,keep track ofhow many times the case ahs beenfired and consider tossing after 5-6 firings. Glock cuts thier chambers very generiously to ensure feeding.

ONly time it could be an issue is if you picked up some used brass at the range, and you have no idea how many times a glock reloader has shot it. And you could get a case rupture. I will take my chances and keep a good eye on my brass.
