I have TWO Viper HS LR 6-24x50ffp. I have had them now for 3 years. They are on a 7mag and a custom 300win, I have dialed them up and down for shots up to 1 mile and they track perfect. It would be hard to find a better scope for the money. I have shot steel with these but mainly use them for long rang doe culling on mangement hunts in Texas. I have also hauled them to Colorado and made perfect shots on elk and 200 & 700yds. They still went back to zero when I returned home

I have cranked them up and shot steel out to 1mile and made hits with them and they repeated.

The only con I could make would be with the FFP for elk hunting low light in Dark timber but that is not a knock on Vortex. Thats asking a Longrange model scope to make fast up close shots(which I did).

I dont have any experience with the HST or PST but in my experience the Viper HS LR 6-24x50 is a great Longrange scope for a person on a budget that will get the job done with the big boys!
