You are thinking of the solution if it were a conventional percussion capped revolver. If it were there are kits that you can buy that include a replacement nipple adapted to take a CO2 cartridge.Do people not use a blast of compressed air to unstuck bullets in cases like this?
if you do fire it, have you got a hand you dont like? just in case
If you have double charged it then seating it lower is going to significantly increase the pressure. Don't take this the wrong way but if you have double charged it in the past and have doubts that you may well have done it this time, then perhaps you ought to review your loading procedure to one where you can see all of the powder charges are equal prior to seating the bullet.Thats always the concern... I have put a double load in it before and is something I'm not keen to repeat.
I am quite certain there isn't a double load in it now.
I did some trimming with a sharp knife last night and can get the cylinder into the pistol now and it cycles, so progress is being made. I'm going to put it in the loading press and see if I can seat the bullet a bit lower in the chamber because at the moment it doesn't look quite barrel shaped for me to be confident to fire it.

I shall have to do a video for you!
Just pull the trigger man!
Another old duffer (since passed) that we had at the club would regularly shoot his ramrod down range. It occurred that often that we kept a couple of lengths of wooden dowel at the range and would simply go and cut him a new length each time.
Fixed that for you.I can't resist shooting the neighbours cat but got to wait until they go shopping on Tuesday...
Wrap some of your Mrs best towels up into rolls, that'll catch that cat sneeze load you have.
Were it I, I'd carefully hacksaw the case head off, or at least enough to get the powder out, then continue cutting the head off. Then use a broken screw extractor (like a Irwin EX-3; which should be the right diameter to grip the case wall), and break it loose from the die. I had to use this method on a Mauser that had a case head separation, and it worked well (different size screw extractor of course).Hijack.
Just thought I’d let you know, I currently have a 223 Rem round stuck in a body die.
They usually come out but raising the ram then unscrewing the die….this one destroyed the case rim instead of coming free.
