Re: getting into the long range game.
Nothing wrong with the 7-08. It will easily get you to 1K with the 162g amax, 168g vld. Not sure if your mag length will allow you to use these bullets as repeaters, but they'll work as a single shot for LR shooting.
The 7-08 will easily kill deer at 600-700 yards with a variety of 140g-160g bullets. Dont know if you plan to use it on elk or not, but I woudln't hesitate to use it on elk at 400-500 yards with say a 160g ab or partition. For groundhogs, look at the 120g b-tip. That will easily get you to 600-700 yards.
The 7-08 is a great cartrdige to get into LR shooting with. Its a lot better then the 308 IMO. Its a lot more forgiving in both trajectory and wind drift with the superior BC that 7mm has over 30. Its very accurate, mild on the shoulder, easy on the pocketbook.
I myself wouldn't mind getting a savage stevens in 7-08 for a backup all around truck gun for everything from coyotes through elk.
