Never done it.
Surprisingly.
Bought my T/C Hawken at about 14.
Heard all the stories about how you can't blow up a muzzleloader
as long as the bullet is seated on the charge.
Read lots of gun articles, those guys were always testing, trying things?
So..
I tried most of the "Don't" things.
200+gr of 3F under a patched ball.
Two balls. Three.
You know we weren't allowed anything but patched round ball, so
I didn't try conical. Sabots didn't exist yet.
Everything, but leaving the ball above the powder.
Never had an issue, no damage. Except some of those loads did
kick a bit with that brass butt.
I'd bet your gun is fine.
Too bad that wasn't a deer.
Can just see a PAGC Barney Fife type all puffed up.
Trying to twist some archery/muzzleloader conspiracy.
