Other than for aesthetics, you won't gain that much with fluting......or maybe it's "loose" that much.
^Agreed^
You'll "loose" more money than weight IMO.
Don't know much about McM "Mtn Rifle" stocks, but if it's designed around Remmy's "Mtn Rifle" contour (which the name suggests) then SuperSeal's advice makes allot of sence to me.
My 17FB has a CZ sporter contour which is pretty close to most barrel makers #2, finished at 22".
Kills everything from Gophers to Coyotes just fine, and carries/handles like a dream.
It's my favorite rifle.
