The general consensus is you can shoot a round ball out of a jugged choked barrel.
The question that you bump up against is; do you want to shoot the gun with all it originals idiosyncrasies or do you want to apply more recent technology?
There is no correct answer because it is a matter of personal taste. :hmm:
As mentioned in another post, I like my shotguns with more modern stock dimensions for wing shooting, however my trade gun is cylinder bored and stocked like an original, which I find better for round ball shooting.
Updating the muzzle loaders to improve accuracy is as old as shooting itself. Peep sights, palm rests, heavy barrels, shooting jackets all evolved to increase rifle accuracy. Chokes, shot cups and back boring are used to improve the performance of modern shotguns.
The drive to “improve” the muzzle loader has led to the modern in-lines, but many still like the charm and challenge of the older guns.
How much technology is acceptable often comes down too which do you prefer; dropping a turkey at 40 yards or calling it into 20 yards or less.
Again it is a personnel choice thing.
