I hand cut the ramrod groove and drilled the hole today. Everything came out good. Made the ramrod groove and hole 7/16" so I can use a hickory rod and not worry as much about breaking it. I also made barrel lugs from an old car fender steel, and soldered them to the barrel. Drilled for 3/32" pins.
Everything fits good so far. Will try and get more pictures soon.looking for a .735" Roundbball mold. Don't want to pay a dollar a ball with shipping.
