My serious paper puncher, Fclass-T/R rifle wears a Burris XTR 6-24x. It is a better scope than I am long range shooter. The 30mm tube, side parallex adjustment and mil-dot reticle are all the "in" things, and I got a price I couldn' pass up.
On the other end, the scope I may be shooting the most these days is a Bushnell Elite fixed 10x, with target knobs and mil-dot. Its on a heavy barrel .22. As long as I shoot past 50 yds with it, there is no issue. It would be nice if it was parallex adjustable, but for less than $200 (at the time) its been more than satisfactory.
