I need to widen some .44 gas checks to get them onto some boolits. For some reason although my Lee 310 gr boolits drop small, the shanks seem oversized.
The best thing I’ve found so far has been a 1/4” socket, but it results in the gas check being a bit concave. I don’t know if this will affect accuracy, but I’d like to find a better method.
Anyone have any tips?
Thanks - Randy
