Sir Scotty A 5.5-pound hammerless, waterproof muzzle loader for Blackhorn 209 or H4198 up to 45,000 psi with, with 1:18" twist, for 300-grain bullet is a winner for sure.
Interesting implications for any .45-caliber rifle work, might find application in turning any .458 WinMag into a muzzleloader when the zombie apocalypse or other chaos comes and make-do must make-do.
IIRC, Woodman Arms offer a "full bore" option or whatever they called it, with cut rifling instead of the usual McGowen button rifling ? I assume this is for non-sabot, non-Power Belt, jacketed bullet that obturates into the rifling ? How is that bore & groove different. What kind of fitting of bullet to rifling did you have to do to get such great results ?
I am stuck on the .45-cal CVA Paramount but might be able to adapt some of your techniques to that.
Ron aka "Rip" for Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary .458 Winchester Magnum, Magnanimous in Victory THE WALKING DEAD does so remind me of Democrap voters. Donkeypox.
