50 yards and beyond is the Burris 4.5-14 E3 or half mil-dot. These are primarily for hunting/all-around usage. The N-S 3-10 can be had for $169 or so, while the Burris 4.5-14s are about $30 more.
The Weaver 6-24 Varminter is tough to beat for more precise shooting. You need to be a "clicker" or know your hold over distances for this type of scope.
Just received one of the new Bushnell Engage 4-12 SF scopes and it appears to be a good one. The 1 MOA reticle is actually quite visible without the stadia being too "thick".
LRX reticle.... 2 MOA @ 10X
