I just bought a .308 Remington 700P and have decided to go with a Vortex Viper PST 6-24X50 FFP optic with the EBR-1 MOA reticle. Since I will most likely be using a Seekins mount (still up for debate)..my question is regarding the Vortex 30mm rings that I can order directly from Vortex when I order the scope. Anyone used these rings and have any experiences regarding their durability under .308 stresses?
