Any help would be great, I am not a scope or optics guru. I have a Nightforce on my M40A3 and love it. I also have a AI 338 Lapua Magnum which I got later on. I have a Springfield Armory Generation 3 Goverment Model 4-16x56 Illm. Reticle I know its not a Nightforce or a US Optics but it is like new and works great but it is designed or Calibrated for .308 Winchester 168Grain Match. Will this still work with my .338 LM or will it never allow me to get a proper zero? Or can i get a zero but may bottom out to fast for long range shoots? Any help would be great I am a student to this.
