Just got a batch of Berger 338 in the other day and started my load workup. First load I tried was 89gr. of H-1000. Grouped well, but the ES was a bit high. The second load was 90gr. of H-1000, it also grouped well at 100yds, and the ES was 21. So I decided to see what it would do at 300 yards, and here's the pic.
Thats a 2 inch orange sticker, and although I haven't measured exactly what the group size is, I'm gonna say it's about an inch. So far I'm happy with the results, and think I got really lucky by finding a good load on the 2nd try.
Here's the specs..
338 Lapua Magnum
Berger .338 300gr. OTM
CCI 250 Primer
Bullet seated +.005 in the lands.
I know its not exactly benchrest standards. But its gonna be a sub 1/2 moa group.. Thats good enough for me!
Got an idea where some unlucky whitetails are hanging out, so I think I will go drop the hammer and see how it performs on game. Although, after seeing pics from another thread, I have a pretty good idea what the end result will be.
