I pushed the cap onto the nipple of the .58 Buffalo Hunter I had.
It went off. Put a big hole into a 2x10 I didn't intend.
The nipple must have been a little mushroomed. That was in 76, so I don't remember, and I pushed just hard enough or too hard.
yes it hurt my thumb and burnt it a bit and a wing stuck a bit into my thumb.
I liked to have jumped out of my hands. I didn't have it on my shoulder.
I've got an Old Army, that the nipples have mushroomed some.
Can't get the nipples out, of the cylinder. Have to be careful not set the cap off, as it requires some pressure to put a cap on.
I'll have to find some way other than a CVA wrench to get them out.
The soft nipples just don't like heat and being hammered.
It is confusing the number of different nipples available on the net.
Some are stainless, which I have for replacements, and some are nitrided, etc and some other metals. Some are several dollars a piece.
