I've got a bull barreled 17hm2 barrel and Im wanting to ream it to 17 hornet or fireball

Rimfire cartridge. The gun cannot stand the pressure of a centerfire cartridge even if you could figure out how to convert it. Goatwhiskers

its a bull barrel made for a frame with offset firing pin but fits perfectly into a centerfire SB2 frame

If the barrel is offset you would have to remove and replace the lug.
the lug could be ground and rewelded to put the firing pin in the center of chamber.

I would sell the barrel and buy a new one.

Im not making myself clear i guess... if 17hm2 was centerfire, the firing pin would strike the primer as it is. but since 17hm2 is a rimfire, the firing pin strikes the center of the casing.

No, you didn't state what gun you are fooling with. Visit www.go2gbo.com and visit the forum for NEF guns. There is far more info there than we could ever discuss in this thread. I will say that you don't just arbitrarily change barrels and frames on those guns, there is a fitting procedure that must be followed for safety and function. Good luck. Goatwhiskers the Elder
