round ball is what i'd try first.
Like I said in my original post, I already tried that. Better but not good enough. The best it'll do is 3-1/2 to 4 inches at 50 yards.
It's time for change. I'm backed into a corner with a muzzleloader elk tag for a season that begins Saturday. After that ... I'm done. I've fought with it at least 5 years off and on. I'm not going to waste more time at the range without either removing the QLA or changing guns. I won't do it with a centerfire and I won't do it with this side lock. Done is done.
