I was under the impression that the mini-30 shot .30 carbine bullets. So did many people I know. When I was younger, I was shown a gun with the .30 carbine bullets which was called a Mini-30 by the owners. Now I look in the ruger catalog and finally noticed how it's caliber was 7.62x39mm. Was that always it's caliber or did the mini-30 previously shoot the .30 carbine and switch over?? And if it always shot the 7.62x39, could the guns that I (and friends) saw which shot the 30carbine bullets only be M1s???

It's funny because I even recal the guns that shot the .30carbine looking just like the mini-30 of the pictures. Was I just simply horibly mistaken or did the mini-30 previously shoot .30 carbine?
