Wow ! Dont' hear that cartridge mentioned often.I know only one guy that uses this cartridge. Youwill find that factory ammo is ratehr scarce and expensive.Remington more or less has long given up on this cartridge, just as they did on the 65 Rem. mag. and 350 Rem. Mag. ... and i suspect will on the SAUM stuff as well. All that aside, this must bea wiz bang set-up. My bud has takenabout every thing in NA with his. And by the way, he long ago started hand loading his 8mm Rem. Mag. ammo.
