I was at the range yesterday, and was looking at all the dumped 12 gauge high brass shells left on the ground,
It got me thinking, if i was to remove the plastic , would you be able to use the remaining cup as a jacket for 12 gauge and .700 jackets?
Might need a larger de rim die like they use for the 22 lr cases...
Sadly importing RCE cups is not an option...
Any thoughts? Do i need to take my tin foil hat off?
