First off welcome to the forum, I dont know how much experience you have had with black powder shooting ,myself Im still a newbie but you didnt mention whether or not you shot off of a clean or fouled barrel and how often you swabbed between shots. Ive found with my Accura it shoots great with a variety of loads both T7 and BH. Also what primer are you using some primers are dirtier then others and cause more fouling. To really get some good backround read up in this forum and several others (Frontier Muzzleloading - MD ,also member here forum has a lot of Accura users) and you can get some good insight in how to get more from your Accura. Patience you only need one shot..
