You mentioned a 1-10 twist. That may handicap you on the really high bc bullets that you can find in 7mm. You should be able to use the Hornady SST in 162gr. The bc is over 500 and will do very nicely on deer and elk. I used it at 525 yards in Colorado and was very pleased.
You can expect velocity of around 3200 fps. That makes for an awesome rig. I did not develop the 140 gr bullets for my hunting because i am in a very open area an a 7-900 yard shot is not out of the realm of possibility. The higher bc 160+ class bullets do put in a performance diffrerence at those ranges. Better to be prepared for the longshot and them make a 50 yard shot than to watch the buck of your dreams saunter off at 713 yards.............
