I used an online ballistic calculator to make up an imaginary load. Cartridge 300 RUM, 200 grain Nosler Accubond (bc .588), muzzle vel 3000, sea level.
Range Velocity Impact Drop ToF Energy Drift
0 3000 -1.5 0 0 3997 0
100 2833 0 2.22 0.11 3564 0.93
200 2676 -2.85 8.79 0.21 3180 2.45
300 2526 -10.58 20.24 0.33 2834 5.07
400 2380 -23.79 37.17 0.45 2516 8.88
500 2241 -43.17 60.26 0.58 2230 13.96
600 2105 -69.48 90.29 0.72 1968 20.45
700 1975 -103.66 128.19 0.87 1732 28.47
The energy is acceptable at 700. Punching in the numbers for the 300 WM (2800 fps) using the same bullet it still remains a valid choice but bullet drop is 120 inches and energy drops to 1473 ftlbs.
The 7mm RM at 2900 fps with 160 gr Accubond (bc .531) drops 116 inches and energy drops to 1156 ftlbs. Energy is acceptable for deer but lacking for elk (this is of course if you buy into the energy arguement). Bullet drop is roughly 10 inches per 25 yards of range between 600 and 700 yards.
Please understand I am not trying to dissuade you from your goal but trying to point out the inherent difficulties in shooting that far.
No mention of caliber.

Again no caliber mention.
I found a link to the guy doing the shooting above and here is his evolution to long range shooting. I am not plugging his product, just paints a pic of what we are talking about.
