kurt, i might be outta line here, as others have proved many times....
but ain't the 22mag on a sportster receiver ? and will it function on a sb-2 receiver ?
are the sportster receivers strong like the sb-2's ? and did they make a 22mag on a sb-2 receiver ?
i do know that the 22-250 has a mighty stout chamber pressure.
or maybe i jus don't understand what your asking !!!
gotta remember that i'm from alabama
