Exactly what Varmint said
Once you start shooting it, then cleaning up after it, you'll give that T7 away!
Although close in ballistics, BH by far is a better propellant IMO. It cleans up with just Hoppe's, like any of your other firearms. You DO NOT use water for clean up.
However......... you should use a magnum primer, either CCI209M or Federal 209A primers. Regular designated "Muzzleloader Primers" WILL NOT give you consistent ignition. Although a regular Win209 will work..... most of the time, its highly recommended to shoot the magnum primers. Using those magnum primers does cause one minor concern, which is it carbons up the flash channel of your breech plug. With your Encore, use a 1/8" drill bit.... TURNED BY HAND.... and just chip out the excess carbon. You'll know when you get to the bottom of the of the flash channel. Its SO.... much worth shooting. I've sat and shot a couple packages of Barnes and never swabbed the barrel. Because I shoot (compete) against myself, I clean the flash channel after about every 10 shots.
You either change to it now or, you WILL later and once you do, you'll be hooked!
