Did some slight testing with 285s back when they were released.
After some quick pressure testing and some rounds through the chrono
I ended up with going with 93gr of H-1000 .065 off the lands which gave
me 2825 fps.
This shot right at half MOA at 400. Then I stepped back to 964yds. First
shot was 3 MOA left, adjusted then sent 3 more. The first two shots were
3in apart then the last shot put the group at 10in. Goods news, the group
was mostly horizontal, the vertical spread was 2in.
The next outing was at 1707 yds with the wind switching 5-10mph. The
target was a 20in gong. After shooting two 3 shot strings, 6 shots total,
ended up with 1 on steel.
Rifle is a 338 EDGE AI 30in bbl. I am happy so far with the slight amount of
testing and load development done. Also like the uniform meplats. Other
than that I have only shot about 6 more 285s at range and it was way to
windy to gather any useful information. The new berger 300s seem to keep
having good reports, will try them out eventually.
I run an edge with a 24" tube 300 Smk typically shoot .3 to .4 moa with a few in the .2 range. They are great and what I usually shoot but the bergers run .2 to .3 with a few in the .1 and run about 30-40 fps faster from the muzzle, They are prettier also........Hornady's cost so much I have not bothered to try them.........Good luck
