It's just a smaller bolt that can cycle and fire a rimfire cartridge.
Wow. I'm definately in.
As long as it doesn't hurt the barrel by having a bullet that is .003 smaller "bouncing" around, it sounds like good, cheap fun. Another thing, how would it seat into the barrel properly?
I am going to do a litte research. Figuring out how stuff works facinates me.
