I have acquired a Lancaster Shot and Ball gun, and after taking some measurements etc. have the following: Bores both at .730, 6 groove polygonal, very shallow rifling. Seems straight and uniform up to about 8" from the muzzle, where it imparts a slow twist, and about a light mod. choke. All this is very difficult to see, and I have no clue as to twist rate.

Came with some modern H&H paradox loads, which have the Fosbery style bullet of 750 gr. lubed with what looks for all the world like liquid alox! Patterns shot well, don't know yet about the paradox loads.

So- I will be ordering a roundball mould, and think about .735-.740 should work. Conical to follow.

Thoughts??
