Martin I think your screwed! I looked high and low for about a year and could not find a thing. McMillan as you mentioned is a scope only option IMO as far as I'm concerned. BTW, fiberglass resonates (sp?) and transfers energy, ya sure you want to put that on a big boomer? I had spent some time with a custom CZ 602 .416 Rem with a show walnut stock and a McMillan glass stock to hunt with. Both about the same drop and comb, ect.ect. Recoil was noticeably less snappy with the wood.I Admit though, stock shape was likely just as much of an influence for each stock...
