[QUOTE="yorke-1, post: 2275685, member: 11960"] I've had good luck Rem brass in the Ultra Mags. I've used it for all of the factory RUM cases as well as a few wildcats based on those cases. I've also had good luck using Norma 404 Jeffery brass to form cases for RUM based wildcats. I imagine he's using the 338 RUM necked down to 7mm for the body dimensions, but using 300 or 7mm RUM brass and pushing the shoulder back to match the shoulder position of the 338 RUM case. This will give you a long-necked 338 RUM case, which should work really well for a 7mm intended to shoot heavier/longer bullets. [/QUOTE]
