Hello all, I'm just about to purchase a Bergara B14 Hunter in 7mm rem mag. I purchased a 1st generation Vortex Viper PST 4-16x50 FFP that has yet to be used. Needless to say, I'm questioning a few things about it. Most notably, I am worried about how well it tracks, considering it is a "lower" end scope. Should I just run with it or should I sell and buy another optic? How can I test the tracking capabilities of it to ensure its accuracy? Thanks in advance.
