[QUOTE="dirtball, post: 448759, member: 7344"] [FONT="Comic Sans MS"][SIZE="3"]Long*range*Lapua With the 12 x 42 NXS if you try to go to a 30 MOA base you will bottom out about 8 to 12" high at 100 yds. If you stay with the 12 x 42 your best option will be a 20 moa base which will be VERY close to bottom at 100 yds, you may have to settle for being a little high at 100 or set your zero at 200 yds. But it will give you 40 to 45 moa of vertical from your zero, which should get you out to 1300 to 1400 yds. When I built my 338 LM Imp, I used an 8X32 NXS which has 65 MOA of adjustment and a 30 MOA base and I ended up about 3 MOA from the bottom with my 100 yd zero and about 60 MOA of vertical adjustment, not that I will ever need it. You should also try to learn the MOA dials on your scope rather than counting clicks. If you use one of the "on line calculators" such as JBM to produce a custom drop chart for YOUR rifle it will make life much simpler.
