Pyrodex pellets are actually great in accuracy. I'd suggest the 295gr Powerbelt with 100gr pyrodex pellets and the Winchester W209 primers. SWAB the bore clean between each and every shot.

TC jags suck, they are constantly breaking off in peoples guns. Their clear view powder measure and powder flask are highly recommended though.

I also strongly suggest the plastic style bore brush VS the bronze brush. They last a ton longer and don't jam up down in the bore when you go to pull them backward.

Warm soapy water at the end of the day to flush the powder fouling out will do fine, along with a good quality gun oil like Barricade, RIG #2, Montana xtreme bore conditioner or their gun oil. Stay away from the seasoning patches and bore butter!
