I've been stirring the pot, about buying a set of case forming dies. I want to put a belt onto the Rigby case. I want to use this in a L.H. Rem. M 700 that's a 338 RUM at present. I think using the Weatherby belted case will force me to butcher my receiver. But swaging a belt into the Rigby case, would make it's swaged down body very close to the .550" UltraMag's diameter.

Has anyone done this? My goal is to make up a belted rimless express cartridge, in one of the fifty caliber variations. It would fall in between the rimmed Uberti 50-95 and the WWG 50 Alaskan. I want to get off follow up shots quicker than I can with my right handed M-98 .416 Wildcat rifle. So it can't kick too hard. I want a short case that I can load to 95% density, and still have manageable recoil, with a heavy for caliber bullet. This bullet can't shrink, and should plow right on through any West Cape Animal, including a bull Eland. Obviously a Cape Buffalo is a different story.

Hunting in a High Rack, and shooting left handed, means you have to keep your two rifles with empty chambers, and un-cocked, as your P.H. has to climb up the side ladder, looking straight down both muzzles. My light rifle is a L H Ruger MKII in 270. But I took Federal ammo with 110 Barnes, and so my P.H. wouldn't let me shoot anything bigger than about 150 lbs. with it. But it was a lot quicker, to bring to bear, shooting left handed.
