I didn't mention the danger of getting a bullet stuck in the barrel, because Cerdan had already taken care of that, very well.
Now, not to add controversy, or get anyones ire up, but just to quote from some of my notes.
At one time I wanted to photograph a bullet as it left the barrel. This can only be accomplished with high speed flash, in the dark.
On Aug. 19, 1985, I set up my Marlin 44 mag as the rifle to try it on. I won't go in to the technical phaze of setting up a trip to release the flash, as the bullet leaves the barrel. I wanted a basement load, as slow as practical, so the bullet wouldn't be travelling any faster than neccessary.
I was using 240 grain cast bullets and set up a wooden backstop, which I have recorded as, "Hard fir cross grain."
4 grains of Unique-- burried the bullet in the hard, fir wood, until the base of the bullet was in ¾"
3½ grains of Unique burried the base of the bullet about 3/8 inch in.
3 grains of Unique just about burried the entire 240 grain bullet in the hard, cross grain fir wood!
This was OK for a load, let the photography begin.
Bear in mind that this was in a rifle, so there was no gas escaping, as it does in a revolver, between cylinder and forcing cone.
Results may be considerable different in a revolver, to what they were in my rifle.
In any case, always make sure the bullet has exited the barrel, before shooting again.
