if the right handed shooter wears his horn on left side how would you prime from the same horn??....instead of lifting the rifle on right side(butt out)an priming from main horn with the double twist that points to the pan then prime.You would have to shoot,then put rifle in crook of right arm,get powder horn in left hand,pull powder measure with right hand off strap,spill powder in measure ,then pass rifle to left hand freeing up filled powder measure to pour down bore,hopefully have a bulletblock an short started in strap to load an start ball down orrrrr,you must pass gun again to fumble in bag for ball/patch with left hand.when you prime with main horn,the gun is cross cheasted to get pan on side of powderhorn.then switch back to right to shoulder the rifle......geeez seems like a lot of left right passing........what would you do if you had to lay on the ground an return fire?onw side would be under you...............help......sonny
