I have the rifle, rail & rings- (Savage 12LRPV 6mmBR 1:8) Shooting PD's at 400+ yards. Hopefully at 800+ yards Targets 200-1000 yards. I have been looking at the NXS 8-32x56 & the 5.5-22x50 or 56. Opinions? Also, on the reticle I'm considering: NP-R1 & NP-R2 should I consider any others? Any & all help appreciated.
