You can easily make precision shots on Man sized targets at 1000 + Meters with a 10X Tactical scope, if the optics are good. As a matter of fact, many of the military .50 caliber sniper rifles are equipped with 10X optics.
Benchrest shooters usually prefer a high powered scope to shoot a a very precise spot at long ranges, but remember, the target is perfectly still & the rifle is resting on a 4" thick slab of concrete.
It depends on what you are shooting I guess. High powered scope are fun to shoot targets with, but highly impractical for real life tactical situations & moving targets. You would be very frustrated if you pick up your nice 22X scope to shoot at a moving target & you have to keep looking above the optic to see if you can figure out where the target went.
The only thing that the high powered optics are good for is Target ID, but a good 40 or 60X spotting scope works even better.
I personally use a 4-16X Mildot scope or a straight 10X Mildot scope. To me, there is only one scope, Schmidt & Bender Police Marksman II.
Some of the Leupold line of Long range M1 variable power scopes might be worth looking into for a few less bucks.
