I didn't read this entire thread, so excuse me if this post is redundant. But I did read enough to find most of the OP's criteria for this rifle.
Let me say I am a fan of the 7mm chamberings. My most favoite is the 7mm-300 win that I have posted about in the past. Why? Because you can get brass that is awesome and it is readily available, it will sent a 180 VLD to 3200 fps in a 28" plus tube. It is easy to change a bushing and use the redding 300 win dies for it, and I feel this case is as far as you can go with out having really accelerated throat wear in a 7mm. It will shoot very accuratly without modifying the shoulder of the highly accurate 300 win that has been respected in matches for years. I really like this chambering and I am doing one for a friend off of a Mark V action now.
That said, it has been mentioned ELK and also 1000 yards. This will probably tick some 7mm fans off but I feel there are better choices for elk at 1000 than a 7mm. 1000 is the absolute limit I put on my 300 win with 210's or 230's and only in near perfect conditions. I say that and my 300 win is a truely consistant 1/2 moa rifle at 1000. But soon after 1000 the bullet is dropping below 1700 fps and at this point it is very hard to get decent expansion of any bullet.
So, for 7mm I feel 800 or maybe 900 yards is a good perfect condition limit. If you want to go to 1000 go with a 300 win mag. Especially with the newly released 230 OTM's. They added about 130 lbs of energy over the 210's at 1000.
If one will ever consider putting the wods elk and over 1000 in the same senario. Get a .338
Just my opinion.
