I would not go with a straight 10x if I could help it. Last year my brother and I were all set for a long range elk hunt. Planned on setting up above tree line and shooting into the oposite mountainside where the timber starts. Well with over 16 inches of snow on the tops we had to go down to 10,800. Thats where the animals were. Luckily I had brought along 2 light guns with 3x9 scopes. John shot his bull at 25 yards in a steep boulder slide surrounded by timber, and I gave him one round to keep him there. A cow was killed on the move at about 125 yards. 10x would have made that situation difficult.
A Weaver Grand Slam in 3x9 can be had pretty reasonably. It dosen't have tall target turrets, but the small turrets it does have can be slipped back to
-0- after sight in. A conquest 3-9 has better glass and can also be reset, but the turret isn't numbered, you would have to count clicks.
If you don't plan on changing hunting conditions as in my case 10x should be fine for anything from 150-1000
