Re: 300 ultra mag
With all your case capacity and the slow burning powder that the 300RUM uses you'd be better of with the 180gr noslers. That being said, if your going to shoot your elk inside of a few hundred yards, I don't think the elk would tell too much difference given shot placement is the same. And yes, the nosler brass would be nice to reload, just buy a few boxes and you should be good to go!
