I misstated the bullet diameter, bore diameter is right around .620", bullet is smaller. I have not checked twist rate or groove diameter since I have the mould. Lubed felt patches and hard wads are both on hand. I have a long enough section of Ebony to make a proper rod but just don't have the time to make one before I hope to hunt this rifle in December.

I may need a help group...3 more British percussion rifles are on the way, 2 Purdey's(.50 cal and a 16 bore) and a Westley Richards(.50 cal).
