I am torn on scopes. I have a down payment on a viper pst 6-24x50 ffp and i really like the reviews on it (hence y i have deposit on one). but after looking around since they are on a forever backorder, I have been looking at the nightforce benchrest 8-32x56 Precision and the Leupold Mark 4 6.5-20x50mm LR/T M1. I am mostly doing 500 yard shooting, but will go out to 800 and 1000 yards. I like the FFP on the vortec but I like the 2 other scopes as well. should I wait on the vortex cause of the ffp or look more into 1 of the 2 other scopes? if go with the other 2, which would be the "better" one?
