The range that I shoot on only goes to 125 yards, but if you can learn your reticle subtensions, bullet drop, how to "dope" wind, etc., then it's possible to make accurate hits far beyond that. As long as you're comfortable, that is. As for glass, I'm using a Leupold Vari-X III 4.5x14. I picked it based on these criteria: I wanted a scope that was capable of the same accuracy as the rifle, i.e. 1/4 MOA adjustments, an adjustable objective, light enough to be portable, available sunshades, matched to the finish of my rifle, and high quality: no trashco, no simmons, no bushnell, no bsa (which really means bastard stopped again). You get the idea. I got it at Bear Basin Outfitters. They beat the hell out of SWFA and have free shipping on orders over $250 [url]http://www.bearbasin.com[/url] I'm going to try some Varget next in this rifle.
