I've reloaded for nearly 50 years and never heard of anyone doing .22 RF. It isn't practical.


For a start, it'd be a puzzle to get the original firing pin indentation out of the rim. So far as I can see, it could only be done hydraulically, and that'd require some precision - therefore expensive - tooling.

If you didn't remove the indentation, you'd be left with the risk that the pin would strike the same place again, where there'd be little or no priming compound - once you'd found some more fancy precision kit to spin compound into the rim like they do in the factories. That risk would increase the more you reloaded the case.

You could probably charge the cases similarly to CF cases, except that your tolerances would be very tight for such small propellant quantities.

Then there's crimping the case on a heeled bullet to the same diameter... the list goes on. All for the cheapest round on the market?
