It seems that the 2oz Hevi-13 loading sell out about as fast as anyone gets them. I heard Presely's didn't have any and that Gander Mtn. had sold completely out. We order ours from Cabela's early in the year. All you need to do is submit your F.O.I.D # and a copy and you can order ammo. Macks Praire Wings also had a fair stock of the Hevi-13 loadings as well. Good luck in your search
