Okay guys I understand not wanting to shoot the Bear, Wolf ammo out of your rifle but it seems both have done a lot of improvements. I shot nothing but US made brass cased boxer primed ammo and my firing pin broke anyway (I am convinced it was a fluke and Ruger took care of me). I bought my Mini-14 because of it's reliability and durability. Do I want to shoot corrosive lacquered crap threw it? NO!! This is not the ammo I see from the Commies now days. Yes it is steel cased but the coating seems better and no more red sealant crap. I admit I checked it out. Fired 200 rounds not a single failure Wolf Black Box Berdan Primed non-corrosive. Guess I was proving to myself that the mini can eat anything. Oh ya what is wrong with Berdan primers?? Only thing I can find is they suck to reload. I wouldn't reload steel anyway so what gives?
