I bought some Blackhorn209 powder and I am thinking about going ahead and drill out the opening in my CVA Optima breech plug.I could only find a #60 drill bit.I heard you should use a #65,Is #60 Too big?You would think a city the size of Toledo would have a place to buy such a drill bit,but No,I looked everywhere.Didn`t really want to send away for one because I wanted to have it done with in the next couple days.
