When I was more of a wildcat guy, I looked at this cartridge 20+ years ago. I liked Jon Sundra and he did come up with a cool cartridge.
Just for simplicity sake and at a slight cost in performance, I just ended up with a 280 Ackley Improved.
If you're really into wildcats, then the 7mm JRS is worth tinkering with. If not, I would just set the barrel back and re-chamber to a 280 AI.

Quite similar to a 7m PRC with a smaller bolt face

So longer coal then a 7 prc with a .473 bolt face? Is it based off the 30-06/it's parent case? Would you need a CIP mag to feed 180+ gr bullets? Without putting the boattail past the neck shoulder junction. Anybody know?
Thanks.
Thanks.
I emailed Randy Selby and this is what he suggested.
