I'm using a 30moa one piece scope base on my 300 RUM and have my zero set at 600 yds, but that is with my scope dialed almost all the way down. I am using a Burris Black Diamond 8x32-50 with 1/8 turrets. If you use a 30moa base, what is your zero set at? I am wondering is I need to back down to a 20moa because I will probably not get the opportunity to shoot much past 1000yds, and I would prefer to have my elevation adjustment some where in the middle. What do y'all think?
