I just purchased a Ruger Precision rifle chambered in 6.5 Creedmoor. I want to be able to constantly shoot 1000 yards. I have narrowed my scope selection to the Vortex Viper PST gen 2 5-25X50 EBR-2C or the Sig Sauer Tango4 6-24x50mm. The Sig is quite a bit cheaper which scares me for some reason. I would like to hear of any experiences with either of these scopes or if you have a better option for my RPR. I believe in the buy once, cry once philosophy!
