Raymond,at last count there was 8 gun makers chambering for different WSM cartridges.I see where Ruger just announced chamberings for the 270WSM.Yes I have a Savage and ammo is not hard to find even up in the boonies of Maine [

]The local Wally World sells 270 and 300WSM ammo for $19 a box.Remington not only makes the Core Lokt but has done several runs of scirroco loadings also.Look for federal to get on this cartridge also as the sales and popularity has been climbing rapidly.I will give you a link to a short mag site that has all the scoop on gun availability and ammo availability as well as most other questions answered.
