Re: 22" or 24" Barrel .300 Win Mag
I agree with jack1k on this one. I see no reason to go shorter than 26" for the .300WinMag. The difference is mere ounces.
If you truly want to drop the weight, go with a "Mountain Rifle" profile, short action, 24" lite contour barrel and synthetic stock, caliber .300WSM. JohnnyK.
