hey guys just wondering how everyone else is doing with their R700 AAC-sd bolt rifles and what peoples best grouping load was ? have been playing with all sorts of weights and just recently started shooting my aac bolt rifle out to 1000 yards . i went to do some new development on 178 amax w/ Varget and havnt found the performance node for my rifle. i've seen alot of people getting 1/2 moa from their aac-sd bolt rifle would like to see what some guys are having better results with . i've been using varget exclusively for my 308 supersonic rounds . all help and data is appreciated. last time i shot 1/2 moa was with 180smks and varget with cci br2 primer and federal brass
