I was pleased to read your comments about the Vortex Viper PST 4-16x50 FFP. I mounted one of those on my .308 Savage fcp hs-precision a little over a year ago and have enjoyed the heck out of it. It retired the Bushnell Elite 4200 that was on the rifle.....simply put, there was no contest between the two.
I hope you find a suitable optic for your rifle. I don't think you can go wrong with one of the better Vortex optics, as you've already discovered.
