Just downloaded the 375 H+H with 40gn RL7 220gn Hornady FP. The MV is 1971 fps and energy 1998 fpe. Zero @ 25m and 100 beyond that she drops like a brick.
Should be great for woodland high seat work. Consider it a massive 243 The lower shot is the initial sighter which I always take at 25m. the next two ie zero are @ 25 and 100m. Very accurate round so no need to shoot groups for this excercise. To go to full power load just add 8 clicks up - what could be simpler
