Alright I have a Springfield Armory scope w/ rangefinding reticle on my M1A and have a few questions. First do I zero it at 100 or 200 yds.? Also what's the round thing on the bottom of where the turrets are (looks like a spanner wrench turns it) (see pic)? I've e-mailed SA numerous times and all they do is send me brochures and don't answer my questions.
Thanks,
Greg
