would like to interchange one decent scope such as this on 3 longrange shooting/hunting rifles in 6, 6.5, and 7mm. if using an moa reticle, how do you know where to set the elevation turret if your rangefinders are calibrated in yards? would you need the G7 type by gunwerks which has an moa mode? are there any other rangefinders calibrated this way, in moa? and, is there any advantage to the 'thin' reticle? appreciate the input.
