.338 RUM vrs .338 Edge

I am gathering parts for a .338 build. I had a .338 RUM in mind, however I have started wondering how much benefit there may be to building an Edge instead. Sorry for my lack of knowledge on the subject, but the Edge is a .338-.300 RUM is it not? What advantage in velocity will I see with it and how difficult is the brass to form? Is it just a kneck-up on the .300 RUM? Is the Edge a propriatary cartridge where I have to get some one in particular to chamber my barrel blank? I was considering a 10 twist, would this still be correct??? Thanks!

I think the edge is at least 100 fps faster with the same bullets, maybe more ? It should run between 2800-2900 with the 300 smk in 30 barrel. There is alot to read on this site, so I'll let you get back to it !!


With each step in the bush, you are a step closer.
