I was doing some reading about the Volcanic rifle the other day. I'm sure most of you know it was a predecessor to the Henry and later Winchester rifles. It used a hollow 41 cal bullet that contained 6.5gr of powder, closed in the back with a primitive centerfire primer. No cartridge case as we know it today.. A pretty anemic, yet revolutionary design.
It seemed pretty simple, so just for fun, I went to the lathe and made up a dummy round using a modified lyman 427098 bullet and a cut off and modified 32 H&R magnum case head. This is it, along with an original Volcanic cartridge.
