Rimfire

[Rocky Raab]

It is possible, but it's neither safe nor cost-efficient.

First of all, the brass is extremely thin/weak, and where it got crimped by the previous firing is even weaker. So a second firing would almost certainly rupture at the first rim crimp.

Second, you'd have to somehow make your own priming mix. That's neither safe nor easy. They don't sell it.

Third, you'd place a drop of the semi-liquid priming mix in the case and spin it really fast to distribute the mix inside the rim. Let dry.

Fourth, you'd charge the case, but the kind of powder they use is not sold. A substitute wouldn't have the right pressure curve: either way too slow or too fast. Too slow means very low velocity. Too fast means the case ruptures.

Fifth, you'd have to make or have made a bullet mould. Rimfire bullets are heel-type bullets, and once again, not sold.

Sixth, you'd have to make dies, including a crimping die that would somehow crimp the case into the bullet without damaging the bullet (which is the same outside diameter as the brass). It'd take a collet type crimper.

Finally, you'd have all this investment - not to mention risk to life and limb - to re-create something you can buy by the millions for about two cents each.

Just 'cause something's possible doesn't make it smart.
