Look at my avatar, that is an old 10X Bushnell with BDC. It used to set on a Remington BDL VS 222 Remington. That rifle took a little load deveolpment, but it would shoot in the .3 range all day once I found out what it liked. I could shoot blackbirds at 250 yards with it. As long as your crosshairs do not obliterate your intended target, you can hit it. Do not blame the scope power. As has been stated, it is a matter of personal taste, but I can tell you it takes more practice to hit well in the field with a higher power. The higher the power the more it translates any rifle movement. I was used to 4X scopes on 22 rimfire rifles. When I went to a 10X, I could not hold it on a target for the life of me, even with a Harris bi-pod. It took a lot of practice to get to the point I could shoot in the field with confidence. The higher the power, the more practice it takes to shoot with confidence in the field, where rock steady rest is not available.
BTW at 250 yards, that 222 with a 50 grain SPSX running around 3000 fps would drift 4 - 6 inches with even slight breezes. If there was any wind at all I would not hit a blackbird on the first shot most times, I would walk them in, when they would duck thier head when the bullet wizzed by then I knew I was close. It would take 3 - 4 shots to nail one, most times, unless the there was no wind and I could hit them every time on the first shot.
Good Luck and Good Shooting
