In my area, the short mags are selling. Especially the 270wsm and 300wsm. Many hunters I'm in conversation with have purchased a WSM calibers when buying a new hunting rifle. Ammo is in wally world so I think this is an indicator.

As for the 338, this is a great caliber.......the 325 performance wise in about the same but comes in a lighter package and I believe a little less recoil. I've fired both and the 338 hit mealittle harder. I like a short action bolt. Ammo in the 325 is harder to come buy but I went to Gander, Cabelas, my local gun shops and they all carried 325's
