My thought on the 2.5x is target acquisition time never changing due to the fixed power. But then again I may just be full of S#!%. The goal is a good, reasonably accurate (hopefully very accurate) quick handling rifle with good punch to be able to shoot to a long range for me anyway , say 250 perhaps a careful 300 yards if time is not a factor. I am not likely to need to shoot longer ranges but the ability to do so when there is adequate time is a plus. I am honest with my self about what is long range and I cant ever see taking a shot beyond 300yds... Mostly cuz I can't SEE detail that well at those distances as well as I would like. I think that for this rifle anyway, a big honking variable would be a hindrance in weight, and maneuverability. I have bolt actions that can be employed if I plan on longer range needs. Just my thoughts...

Be safe and shoot often
