Hat tip to Bryan S. for sending this to me. Doc Nickel does some machine work on paintball guns and various other projects. Once in a while he works on firearms. He helped a client resurrect a circa 1860 Remington rolling block. It is black powder but uses brass cartridges. However the previous owner bored it out for something ridiculous. Doc suspects for 24ga shells.
Client was working on an old blackpowder rifle, an 1860’s-ish Remington Rolling block. As I understand it, they were originally available in a variety of calibers over the years, but this one was originally a big bore, something like .58 Berdan, if Wikipedia is to be believed.
That’s an actual brass cartridge, by the way- it’s blackpowder, but not the old flintlock type stuff.
However, at some point in its’ long history, some nutball had drilled out the chamber- it looked like they just ran a big drill bit in there. Given the measurements of the new chamber, the owner suspected it had been drilled out to take 24 ga brass shotshells.
The new chamber was way oversize for any self-respecting cartridge, too long/deep to accept an actual cartridge of the same length (due to the shell having to angle past the breech block) and was eccentric to the bore. The owner wanted to save it, mainly for the challenge of it- the rifle was in no way any kind of collectors’ item, and had no sentimental value. He just wanted to see if he could make it go boom again.
He brought me the barrel and we plotted a bit on a few course of action. I finally decided to sleeve the chamber with a steel insert (which, as it turns out, I got no pictures of- as I’ve said, things have been hectic around here.) And then, recut the chamber to something entirely new- the .58 Berdan would have been anywhere from 3/4″ to over an inch too short, depending on which version we might have used.
So I invented a .58 Berdan Long. Sort of. As I could control both the breech and the brass, I worked up my own dimensions. Here’s what I came up with, flanked by a blown-out .405 Winchester case, and the 7/8″ x 2-3/8″ brass blanks:
He made twelve cartridges.
I completed these a couple weeks ago, but last week had a chance to go actually shoot the now-assembled rifle with the owner. The long-barreled monster had at some point been (crudely) cut down to something resembling carbine length, with the matching heavily cut down forend stock. I had to trim off another 1/2″ or so to get rid of a dent and to square up the crown, and the owner had added a bit of embellishment to the furniture.
The rear sight is an old 98 Mauser part, if I recall correctly, and has a cool sliding mechanism that raises the rear blade up almost two full inches. The owner wanted it modified and attached to the barrel, which I managed to do reasonably cleanly. Probably somewhat optimistic, though I have no doubt if one lofted it enough, that big 400+ grain bullet would actually fly some 2,000 yards.
I got to fire three shots of this monster- we were getting around 1,400 fps, which is pretty respectable.
It did surprisingly well.
