bigcountry is one of the few that uses his scope like I do. If you start cranking around on those tascos, cheap bushnells, simmons, BSA'S, etc.... I can almost guarantee it will not return to zero every time. I use Leupolds and have no problems starting at 100yds and walking mine all the way out to 1000 yards, and back to 100yards.
In the days before affordable laser rangefinders, I could see tha arguement for cheaper optics, but if you are gonna play at longer ranges, you better get a good scope!
