From what I do understand a rifled false muzzle matched to the rifle bore by the pins will result in a mis-match-, an offset where( expressed in degrees of rotation) the rifling lands meet.
I think you mean to say is that, the barrel is only rifled after the false muzzle segment is match drilled and fitted to the barrel and the false muzzle and barrel assembly are rifled as a whole unit.
We don't have the tools,equipment and/or experience to rebore and re-rifle the gun so for now an approach of
smooth bore for false muzzle has to be utilised as it is all we are capable of.
Only time will tell.
I started muzzleloading in the 90's but my friend started in the 70's and has two national tiles to his name using a scratch built flint lock rifle with components purchased from TOW. Certainly he and I are not novices and have been around slug guns but not owned and shot them in competition.
Half the fun is experimenting to understand what works and what does not.
