Hello everyone,i’ve gotten interested in muzzleloaders in the past year and now have 3,a 32,a 45 and yesterday i picked up a 50. It’s a Thompson Center but it’s stamped Fox Ridge Outfitters on the barrel. I think it’s a White Mountain Carbine due to it’s short length. I’ve google searched but come up empty on information on this gun. It is percussion cap and has a tang mounted peep sight. Would anyone know what the twist rate would be and what would shoot best sabots,balls or maxi balls?I have a Lee maxi ball(?) mold that weighs 320 grs.,i’d like to use that if possible. If someone could give me any info on this gun and why it’s stamped FRO i’d greatly appreciate it.
