I was looking at Vortex optics, and have heard good things, and the clarity is great. For LR is a 10x sufficient? I was looking at the PST, and regular Viper. I can get more power with the plain Vortex Viper 1", and I'm fixed on 2nd Focal plane, in MOA. It will be a paper punching, and LR whitetail gun, and probably nothing past 600yds. Any other suggestions? I have a Leupy 6.5-25 on my LR AR, and a 6-18 on my SVSSFII (22-250) and just recently a Weaver Tactical 3-15 on my 243 SPS in FFP. I guess I will trade my new ACOG in on the optic to SWFA, because if I trade they will do $850. Main ? is "10x enough to 5/600yds?"
