Re: 300 win mag vs 300 RUM

That's an extremely generous estimate, much more like 500-750 rounds.
At 1500rd not making something a viable caliber you would be ruling out all the 6.5's larger than the Swede case (284 case, 30-06 case, 280 case, etc).
I've watched several 300 RUM with 26-28" barrels push the 208's until they explode coming out of the barrel, north of 3300fps while 3000fps can be hit with a 300WM and a 208 Amax, though 2950 is a more reasonable goal for most shooters and rifles.
Barrel life on the 300WM is about 3000rd for some people, though I've seen several go as high as 4500-4700rd.
For 800yd and less I think that James' advice on a 30-06 or 308 is very sound. My personal choice would be a 30-06 since it still has enough capacity to reasonably throw the 208 Amax.
