the reticle was something of a toss up, though maybe a slight edge to the Viper. I liked the FFP on the Vortex, but I really like having 100 MOA of adjustment in the SIII, though the 75 in the Viper isn't bad and, with the 20 MOA rail I already have, it shouldn't be that big a deal.
for some reference, I'm currently running a Nikon Buckmasters 4.5-14x40. I LOVE the glass, but the objective is smaller than I want, and the 60 Minutes of elevation are limited enough to worry me when it comes time to try a 1000 yard competition. Hence my upgrading, though I'll rarely be even competing beyond 600
Thanks for the information so far...it gets a little nerve wracking when the scopes are so close in quality (from what I've seen)
Both say they have a lifetime warranty, how does their warranty service stack up against each other?
