Hello there deerkiller13. 250 yards is a pretty ambitious goal. I'm no good at all past 175 yards. You need to give us a little info on your background. Would this be your first muzzleloader?Are youexperienced withcartridge rifles? If you are already shooting, what gun/loads/distances have you shot? You might want to start a new post with your question, and provide some background informaton. I'm sure the guys here will have lots of advicefor you.
