Bought an Adams and Co 8 bore, pictures to come when it gets to me.

My question is, I had JJ slug the bores and they came out .838/.839. What size ball and bullet mold would you guys recommend?

I am looking at ordering a couple of different bullet molds from Accurate Molds for a 910, 1170 and 1320 grain mold with him sizing the bullets to .841, and the Cast Bullet Engineering .842 round ball. Any thoughts?
