C.J.,
I won't comment on .308 for Moose, but I can give you some insight into my Stealth in .22-250.
Although I did go through the gun with my usual accurizing, i.e., lapped the lugs, installed a Timney trigger, and glassed the action even though it has the alum. bedding block, I have been very impressed with this rifle.
It is by far the most accurate rifle I have ever owned. The only rifle which has printed .3" groups for me. I have had some problems with my Winchesters of recent manufacture, but this rifle is not one of them. I suspect that the .308 version will be a tack driver. Damn heavy for humpin' through the boonies though! Best of luck with it!!!
