Some time ago I mentioned a little project I was tossing around. Since I have done a little experiment with reforming .22 Hornet brass (Kindly provided by Magnumwheelman) to make a new cartridge, a straight-walled, rimmed centerfire .25. The idea was to make a reloadable replacement for both .22LR and .22 Magnum (depending on the load.) I even made the first cartridge as a 'proof-of concept.' I labelled it .251 TCR (Tinker Centerfire Rimmed.)
(Top) .251 TCR, shown with a .38 Special cartridge for size comparison.
I figured at some point I would make a single-shot pistol to develop the round some more, but there have been a lot of distractions, and I keep forgetting to by the .25 ACP 'donor' dies... Then a Colt 1849 Wells fargo reproduction got dropped in my lap as a sweetener in a deal, and it got me thinking. Naturally I would do a cartridge conversion, and I've already done one as a .22... why not make it in .25 ACP? Then I could work out the bugs with a readily available cartridge and set it up for the .251 TCR later. Seems like a good idea. I turned a cylinder out of some half-hard 4140 round bar, cut the lock-notches and sprocket for a six-shooter.
Here's the gun with the new cylinder mounted. I need to make a breech-ring, probably out of 5160 spring-steel. I also need to do the barrel-liner and mount it before I can line-bore the cylinder and cut the chambers. After that I can run my .251 rifling-button through the lined barrel. There's a good bit of work left to go, but, I am pretty jazzed to finally be getting started!
No, I did not cut off the barrel. That's the length it was when I got it!
