A most excellent resolution.
To the best of my knowledge (after talking to the folks at Stoeger), the "Gray Wolf" has been discontinued, with the "Hunter Laminate" being the replacement. The Gray Wolf no longer appears on Sako's website. From the photos I've seen, I prefer the Gray Wolf stock (though they're supposed to be virtually identical). The Hunter stock looks too brown to me.
I would sell my first born to get a Gray Wolf in 25-06, but as he's 18 he's not worth a whole lot on the black market (
). I've been looking for one (on and off) four three months and can't dig one up.
