yes, you are right, don't know much about encores - way back when, people wanted to hunt black powder seasons but didn't want the muss and fuss of patch, ball, patch lubricant, caps that tended to get wet in the rain, powder horns, possible bags, and walking around the woods in 1840's clothing or leather. They just wanted to hunt without all the muss and fuss. Now they have to have the proper barrel plug, the right powder pellet that can't be crushed and has the black powder primer attached to the rear which means that they have to insert the pellet the correct way or it won't go off, worry about their pellets getting wet because even if they dry out they aren't usable, the proper sabot, the correct choice of the hundred's of bullets, the propper tool to take the plug out so they can clean the barrel, and a crud ring.
I have discovered an easier way. Pour powder down the barrel, put a patched ball on top, put a cap on the nipple, pull the trigger.
