Wildcats off of 6.8mm SPC?
Was at the range recently and happened to pick up a spent 6.8 Rem SPC cartridge. Neat little case. If necked down to .224, looks like it would be nice compromise between the .223 Rem and .22-250 Rem. Faster than the .223 but not as hard on barrels as the .22-250.
I'd expect wildcatters have already been necking it up and down. What do they call the .22 version and what kind of velocity are they getting?
