I bought a disc extreme a bit ago when knight had them on sale. It came with the fpj, I changed it out for a bare primer with new breech plug and adapter from ssk. I swapped that out the other day. I haven't got it to the range yet, just been messing with it here in the house. Is the only way u can put the primer in is releasing the bolt pin and sliding the bolt farther back. This is the first disc muzzleloader I've had. Might sound like a dumb question, but just wondering? Thanks for your time! Darin Probably didn't need the pics but anyway. U can see bolt all the way closed, open as far back as the bolt will go, and with the bolt open with the bolt pin . Even with it open all the way, still not gonna be easy getting a primer in there. Just wondered if there was an easier way!
