Get yourself set up with smokeless. I have two hawkens (54 and 50), a bunch of cap and ball Italian revolvers and several original 1860's cap and ball revolvers.
I like the cap and ball stuff, enough to own some original guns, but the smokeless is more reliable in wet weather.
When I care about the hunt more than the implement I'm using, I grab the smokeless rifle (Savage ML-10, works fine)
If you really want to make it hard on yourself, hunt traditional archery.
