What diameter has original Smith shooters been sizing their bullets to? The bullets I cast come out of the mold .518. I am going to try sizing to groove diameter in an attempt to increase accuracy over what I am getting now that is unacceptable IMHO. I want my groups to be at or smaller than a clay target. I am too lazy to slug the bore, that is why I am asking first. If it comes down to it, I will slug the bore. Thanks in advance.
