I need a action that can handle a 4 Bore. Does anybody knows who makes them or as a design of one that can be copied? Any inputs will be appreciated.

There was a gunsmith in Montana, I believe, that I spoke too about scaling up a farquy copy that he builds to suit an 8-bore. I don't think he would have a problem scaling the action up a little more to suit the 4-bore. I had a hard drive crash and I lost his information but if I can find it, I'll post it here. I believe he wanted $8,000 for a barreled action. Not bad for the amount of work involved.
