I now have my Recknagel 70 moa mount so , in theory , can get my 338 well past 2000 yards.
I have been running 250g Scenars out to 1300 / 1400 successfully with 95g of N570.
How about the next stage...ie beyond 1400.
Litz states that the 300g Berger or Scenar will out-perform the 250s until 1500 yards but beyond that the 250g is the best bet in being shorter and so more stable into the transonic range despite entering transonic earlier.........who am I to argue with the guru of ballistics!
As the Berger 300g seems to be unobtanium I am about to order more Scenar 250gs.
