The reason I asked is that I own a newer Mini 30 and shoot commie ammo out of it. It is very hard to find non commie 7.62 mm X 39 mm. A very good friend and local detective investigated a shooting where kids were shooting a SKS and the bullet bounced and hit a girl 283 yards in the hip and put her down. He was very impressed by the 7.62 round enough that he wanted to shoot a Mini 30. I had a new one so we shot it and the accuracy was very good with iron sights being shot by "old eyes". We were interested in seeing what it could do with good ammo. I finally found Hornady ammo this winter and we will put a scope on it and see. If a person has a Ruger Mini 30 they are going to shoot commie ammo out of it and Ruger knows that. The Russian 7.62 X 39 mm doesn't even use a .308" bore. I find it hard to believe Ruger has a softer firing pin than brass primer. I think there is something else wrong with your rifle. I and my friends have broke very few Rugers but when we did Ruger treated us better than you were. Sorry for you problems with them and your rifle.
