Not to jump into this thread (but I will since you're here talking about it already
). I have the makin's of a long range rifle here and I was thinking of just going with the 338 RUM cartridge but your 338 Edge really has me curious. I have a fairly heavy .338 caliber Rock Creek barrel, but it is only a 28" blank, along with a nesika V model single shot action. With probably only 27 1/4" or a hair more of usable length on this barrel would I gain much with the Edge version or would the RUM be perfectly suitable? I'm building a rifle for 600+ yards, most likely with an 800ish yard max for elk (depending on the performance of myself and the rifle of course).
I could possibly sweet talk a friend out of a 30" barrel in exchange for this one (both Rock Creek 5R barrels) of a little heavier contour, but I didn't want to have too heavy of a rifle.
Your recommendations would be welcome (and any others in the know)
