Glock 10mm head separation on about 3rd loading
Only with Nickel cases and about at the 3rd reloading. Partial case head separation on friends gun is bad thing, just after switching to loading with nickel cases he said. Careful loader for many years, but obviously somethings wrong here.
What,other than a huge overload, would cause this. Those gasses don't play nice in the magazine area. Maybe opening too early, greasy chamber, ???
