RE: maxi hunters....
I shot a few deer with them in my knight wolverine. I couldn't keep them seated on the powder. Kept backing off. Some guys on the muzzleloaderforum.com said to wrap them with zig zag paper or tephlon tape.
Once, I was coming out of my tree stand and lowered my gun muzzledown. And saw the maxihunter at the bore of the gun. Just watch out for it.
