Those 50cal Encores are the pickiest muzzleloaders I have ever seen, but when you find the right load they'll shoot. Know a few that have one and some load 100gr loose or pellets with around a 250gr bullet and one with a 285gr barnes. A couple shoot 120gr Blackhorn 209 with a 285gr or 300gr barnes. Not much specifics on load info you looking for just mentioning what I have seen out of them over the last 20 years. I will add this, my friend has one shooting 120gr Blackhorn with a 285gr Barnes and it will eat the middle 4" of an 8" steel plate up at 250 yards all day long.
