That's great. I have heard over the years a number of times, that the original, or might even have been the reproduction Whitworth Rifles shot just as well with round projectiles as with hexagonal ones.
Are they to be paper patched?
Does the literature suggest a lube cookie? That would indeed
help keep the fouling soft for subsequent loads. You should not have to wipe between shots.
Powder, then VERY thin wad - tissue or bee brood foundation like Curly uses, then grease cookie, then thin card - say .030", then the bullet.
The idea is that the powder flame must get at the lube cookie to liquefy and mix it with the fouling. This works a treat in ctg. guns and should be no different in the ML.
This is exciting.
