I have a number of 4X and 6X scopes and still find them quite useful. I'm not a follower of the sniper fad and can't imagine taking a game shot beyond 400 yards, regardless of scope magnification. Several years ago, I did some comparison group shooting at 300 yards using the same .308 rifle, switching scopes from a 6X to a 10X. I fired 4, 5-shot groups; 10X group average was 2 1/4", 6X was 3 1/8", not much difference.
I use some variables for hunting, mostly 2.5X-8X Leupolds, but leave the magnification at the 8X setting from when the rifle was zeroed. I've seldom found a need to alter the adjustment in the field regardless of range.
While there are certainly legitimate uses for high magnification scopes, many of us don't have such a need. A lot of younger shooters and hunters seem to know nothing about lower-magnification fixed power scopes. It seems that many today think lots of scope power and light triggers make up for a lack of shooting skill.
