Hopefully someone can enlighten me on throat or lead angle.
Im looking at 22wmr reamer prints, not exactly BR stuff. It seems most of the sporter chambers are 15 deg and there is a match reamer than is 1.5 deg.
What affect does this angle have normally and why would one be better than the other. Obviously i keep hears 2 deg for the 22lr reamers but i dont think ive heard why.
