I am in the process of restoring a 4 digit serial number 1873 Winchester in 44-40 cal. Have to re line the barrel and the dia is .428 and twist is 1 in 24. Assuming I need a .429 mold for this and pure lead boolets? Going with black powder of course since that’s what it was designed for and I love the smoke.... Any favorite loads out there? Lube? Hunted with a side lock .54 Hawken and double barrel 11 gauge shotgun all my adult life but this cartridge stuff is new to me. Thanks in advance!
