You are right.....I read my exbal chart incorrectly or I loaded some data incorrectly. When I ran the numbers again, I came up with the same results as you for the 300WinMag shooting the 210VLD at 2700fps.
So I will amend my earlier statement and say that the 300RUM is the better choice as it shoots the 210VLD at 3000fps with 1470lbs of energy at 900.
Two other notes....
In terms of accuracy, someone posted the accuracy requirement. I always follow the rule of thumb that says your field accuracy is only half as good as your bench accuracy. This means if your rifle shoots .5 MOA on the bench, you're going to get 1moa in the field (given all the other factors - less than solid rest, adrenaline pumping....etc). That means, for long range shooting, I would accept no less than .5moa for a rifle that I wanted to shoot 1k at an elk.
Also, I agree with woolecox...if the rifle we're discussing does not have the HS Precision stock already on it, then I would not go that route. I would find a less expensive rifle and build it up from there. I've gone this route twice.....
This started out as a Rem700SPS and cost ~$1300 when complete..... http://www.longrangehunting.com/foru...ld-pics-43510/
This one started life as a Rem700 Mountain Rifle and cost ~$2000 when done... My 280 - Updated!

At a 1000 yards the velocity is 1487 and the energy is 1031.
In my opinion the 300 Win Mag is a very good elk rife out to about 800 yards when hunting above 4000 ft. To go farther the 300 RUM is a better choice.
