hi thank you so much for that info on the ammo. i did check out cases an they are all boxer primed. i also clean all my firearms with the old stinky gi bore cleaned as i have about 10 quart cans of the stuff from the estate i picked up. it works great on alot of different items beside firearms too. still tring to decide weather to clean up carbine or leave it as it sits. i was worried that the import mark bent the barrel but i think it shoots great.
