Been looking all around for some 180 grain Barnes TTSX ammo for my 300 Win Mag. Boondocks, Cabelas, Sportsman's Warehouse, Great Northern Guns, Alaska Ammo, even Midway USA is out of the stuff. Everybody says it's on back order and they have no idea when it may arrive. I know this is a popular round but dang. Anybody have any idea why this is so hard to find and when we might start seeing it again?
