I've been thinking about the drawbacks of the .22WMR. It's a great little round, except, like other rimfires, doesn't always go bang when you pull the trigger. It would be nice to have a centerfire version. If there isn't one already, then I just created one.
- It's January, cold, gloomy and damp outside
- Because I can
- why not?
- Any gun chambered for .22wmr can be made to handle the centerfire version w/ just a tweak to the bolt
The .22 mag case is big enough to hold a small pistol primer. For proof of concept, I took a once-fired case and drilled a primer-sized hole through the center of the head. There is still enough of a lip left to do the second part, which is...
Take an existing centerfire cartridge and cut out the section that has the primer pocket. Turn this down to the point where it fits into the .22 mag case prepared above. Slide this down to the bottom of the case and you're ready to go.
With just a drill and a Dremel, the first results are a bit clumsy. It'd be a lot easier with real tooling.
Next steps will involve a bit more work, like picking a powder to use, re-assembling the cartridge, and actually finding a way to fire it. I'll be looking for an old bolt-action .22 mag to tinker with.
Any suggestions as to powder, and how to assemble the cartridge w/o hurting myself?
Has anyone done something like this before? If not, do I get to name it? If so, it's the .22mmc (.22 Monaco Magnum Centerfire.)
