Grafs has the ammo on sale $37 a box .One guy has brass on Gunbroker $65 /50 good luck .That's why I don't like new cartridges made from something you can't find brass for .I just made a bunch of 338 win mag out of 7 mm rem mag .I make my 264 win mag from same brass .Get all the ammo and brass you can for that gun won't be any in ten years or less !
