I build a 500jeffery on a p14 action. The p14/m17's are by far the cheapest true magnum action. I have another p14 action stashed away for my next big bore. Probably be 416 rigby. I would love a .577 but as Darryl was saying,i cant do that any more.

I had a 7 bore muzzle loader and my 460 weatherby caught up in that bull shit.
