Avoid the SAUM cartridges...they're headed for obsolescence.

If you're sold on the Remington 700 I'd recommend the .30-06 as a minimum and the 7MM Rem Mag applies as all of that. The ADL and other models considered but these are long action guns. Remember you said "bigger than deer" game.

In the short action guns maybe the WSM cartridges are good but such cartridges as the 7MM-08 and .308 are still very well known and proven rounds for things to moose etc. I'd prefer the .30-06 but the improvement is small indeed.

The .30-06 suffers from being so common. It's not new or flashy or impressive to say. Make no mistake about it.....this is one very serious big game hunting round and with today's premium bullets and reloads it's better than ever. There's a reason that half the closets in the USA (and maybe the world) has one!!!!
