That's a concept I've been thinking about lately also. I have several LH M70 Classics, all long actions and same barrel contour. I'm fine with the wood stocks for most of what I do with them, however if I ever get to do a more remote hunt again, a tough synthetic would be a benefit. Since I'd only take one rifle, what's the sense having the rest of them sitting back in the safe wearing $500 stocks? A single McM stock swapped between the different caliber barreled actions makes sense to me, especially from a monetary standpoint. As a matter of fact, a couple years ago I bought a Stainless Classic barreled action in .300 Win Mag that was at one time part of a two caliber "kit". The fella had two barreled actions and one stock (don't know the brand) fitted into a ZERO aluminium case.
