So to keep from going nuts " actually started to shake today lol" i loaded up the Wolf with 60gr BH209, .018 patch and .490 round balls and went shooting.

After the shot i normally leave the spent primer in the plug to keep the powder dust from dirtying up the frame. Works great with sabots and conicals.

not so much with round balls!

I pushed a ball down and left go of my range rod and the pressure shot the ball back up off the powder charge and the range rod darn near knocked me under the chin!

I pushed it back down and it held, broke the action open to install a new primer and it shot the primer out of the BP and the air pressure went,, pssssst!

THAT is how tight the seal is now after adjusting the firing pin bushing correctly!

Should be water tight too i would think.

That is pretty tight. No air escaping from the bore or the breech. Me thinks you should not leave the primer in when you load. This may also be happening to a lesser degree with your other loading also.

i normally hear the air come out around the conical/sabot as they do not fully fill the rifling like a patched ball. Tomorrow when i go out i will make a video of the loading and show you how much air pressure is in there. It really surprised the heck out of me. I started laughing when it launched the primer out when i broke the action open.

That's the nice thing about shooting flinters, the vent is built in...

So, you telling us the primer was pssssst off when you opened the breech?

OTHER POSSIBLE COMMENTS:

That primer was probably pssssst off because you poked it with the firing pin.

What primer were you using. Some are more sensitive than others. CCI's are tougher than most and never get pssssst off.

Being used in a CVA would pssssst off any primer. (Uh-Oh, that's gonna draw fire. )

now semi i know you're not that old, u can follow along fine
