If it will fit the magazine box it will work. I see very little ballistic gain from this over the 338 WM, but as long as you're having fun, go for it. Sure you need a 338? Maybe a 8mm PMM is what you really need, ;). I've played with few wildcats on the 300 WM case (7mm, 264, 9.3). They have all worked out well, though you have to be careful about col and magbox length. Other then that, smooth sailing. - dan
