Alpha, that is the nice thing with some of the aftermarket action makers. You can get short actions, short bolt throw. Problem most are Single shot actions. If you need a repeater well not as much luck. There are aftermarket actions with the .470 bolt face that will extract the 440 head cases. Drawback with a 440 bolt is you are limited to those case sizes unless you have a lathe or someone with a lathe to rebate the rims. A lot cheaper than a second bolt. I have a 30 BR that I shoot in a PPC boltface. My barrel guy rebates my cases. For me. I need to find a small lathe that will fit the cutter I had ground and I could do it myself.
