    I have been busy shooting and trying to develope a load for my rifle. I have had help along the way from a friend. This is my best to date at this distance. It's only a three shot group, I chickened out and didn't fire my last three.

    1070 Yards
    91 Grains/2.981 BTO

    Vertical looks promising.

    Reshot the 91 Grains of H1000@2.981. Also shot 91.5@2.981. The 91 was the better of the two groups. I have a few 92's to try, but that will have to wait for another day. I'm assuming 91 will be my go to! Target was set at 1070 yards. I was very happy with my cold bore shot. My square is 5".

    Thanks! Debating moving the bullet out a little more. Try to tighten it up a little more. Group was under .5 MOA.

    I reshot the 91.5s @1070 yards. I had about the same results. The group was ok, but the vertical was greater. I'll be sticking with the 91s. May move them out .002 more and try again.

    I did a little validation @1360 yards and then shoot a mile. This was my first attempt at a mile with my .338. I'll definitely try this again!

    59.25 MOA/1.75 MOA L (Too Much L)
    After validation, 2862 FPS.
    91 Grains H1000
    2.981 BTO

    White circle is roughly 24"

    I forgot to post about my last outing! My accuracy load is 91 Grains of H1000@2.981. I loaded a handful @ 2.983 and reshot @1070 yards. Needless to say I was surprised as I didn't even hit the target. Not really certain how or why .002 would make that much of a difference, but something went wrong. Checked everything, everything was tight. The only thing that changed was that I pushed the bore for carbon, with botetech carbon cleaner. Nothing new as I have done this before. The last time I did this was 70 rounds ago. Loaded up my last 14 rounds back at 2.981. After these, I'll be at 200 rounds fired.
