Hello! I’ve been sketching on a small over/under derringer with the capacity of four shots. I’ve seen the superimposed concept on the forgotten weapons channel, and I thought it’s pretty neat. But I’m curious of what could go wrong.
Here’s a picture of a barrel and the loads https://imgur.com/FgzHsmQ
The second charge has a ”case” to support the bullet, to prevent compression of the second powder charge. I don’t know if that’s necessary? The old superposed weapons didn’t had it.
I will also be using a light (about 100 grains) load of buckshots (with about 20-30 grains of BP/pyrodex P to propell it) for the front charge which should keep the pressure down. And for the second load I will use a slightly overdimensioned pure lead roundball instead of a patched one. For extra sealing I’ll use some Blu Tack behind and thick paper infront, but maybe something else will work better?
Feel free to give some thoughts on this one.
