I've had a Leupold VariX-II (now the VX-1) on my Ruger .270 for 7 years with the zero never going out by more than an inch. At the time it only cost around $200 dollars for the scope. I know it seem's like a lot of money to the younger hunters but at only $60 dollars more than your bushnell, it is well worth the investment. Plus, I've heard the customer service of Leupold is outstanding (although I've never had to deal with them myself).
