I use 60moa base using a Nightforce NXS 5.5-22x50. I bottom out turret that way I have all the elevation the scope has to offer. The very top line of reticle is my 100yd, middle crosshair is 700yd. I can take this combo out to about 2600yds using all the elevation in turret and reticle. I cant see the need to shoot the 338 Lapua under 1000yds once I get load worked up. I use the Berger 300gr bullet going little over 2800fps.
