My first one is a 40 tappered 32 inch which I use for ofhand shooting, groups into one ragged hole at 50. My second is a 62 tappered with an English style pattent breech still under construction, hopefuly ending up looking like a John Manton halfstock flinter. Shooting partners have some of Jims barrels and they all shoot great. One is a 62 that prints 3-shot clover leafs at 100 yards.
