I recently joined up in Dec. and have spent numerous enjoyable hours reading past posts. I am new to muzzleloading and am wanting to build a Penn. style rifle in .54 cal. Have many yrs of custom cabinet and furniture building under my belt and a small shop, also some minor machinist skills from farming as well. Wanting to buy parts and stock blank but a bit overwhelmed if I could handle the swamped barrel inletting. Thoughts and advice appreciated.
