I know it's ridiculous to reload .22s except for "just because" Haven't done any, not that desperate ! ( Guess I'm a hoarder as I always bought 22 in case lots ) . Did "reload" some primers a few years back just to see if they'd work.
The firing pin indentation on the rim seems to make rapid fire improbable with any reloads- could a jig setup be made to force the rims of empties back out with hydraulic pressure ?
Obviously I have too much time on my hands to even think about this !
