Mills, once again beautiful rifle, love the wood... fiddleback looks great on those older style firearms.
Flash LB, I've got one of those CVA "frontiers" also, a friend gave me, after helping him set it up, and develop an accurate load for deer. Damp weather ruined him on traditional BP models, and he graduated to an inline!
GBIA, you can make it as light, or as heavy of a load as you dare! Hang fires, can be expected, and with the "smokeless"/"improved" black powder substitute, not quite as "dirty".
One has to try it, just to appreciate what our forefathers had to endure a couple of centuries ago... and better with a flintlock, than a caplock, but both can be aggravating in damp environments!
