Quick question. I've got a lot of C&R type rifles and am not afraid of or opposed to using corrosive primed stuff and cleaning. I've got a pristine Enfield and M39 that i've never run corrosive through as they both came with a fair amount of commercial ammo as part of the purchases. I'm out of the commercial 7.62x54r stuff and my local gun shop has a pretty good sale running on the golden Bear non corrosive steel cased stuff. Anybody have any good reason why I shouldn't run this in my M39?
