I decided to do the same thing as I did last week to see how consistent I could be with my 338 LM. I was very pleased with the results and I even did better at 1780 yds as I got two out of 4 hits at the distance as opposed to no hits last time. Pics and explanation below.
1st clean, cold bore shot is the hit right below the white bullseye. Moved back to 1200 yards and 1st shot hit is the shot below and to the right of bullseye in the 10" orange circle. Moved back to 1300 yards and the 1st round hit is somewhere in that 5 shot cluster off to the right of the orange. After seeing that I hit, I fired 3 more rounds as I did last week. I was pretty excited to see that they were all close together and still within the kill zone of an elk if my point of aim was right behind the shoulder. I wasn't going to go back to 1780 yds like last time as I had missed all 4 shots from there that time. But I got to thinking that I wont ever learn anything if I dont do it. So I moved on back to 1780 yds and took 4 shots. The first shot was high by about 1 MOA but dead on for windage. I moved down from 57.5 to 56 MOA and took another shot. It was just a little low. So I dialed up to 56.5 and HIT! It hit in the 4 shot cluster that I took at 1300 yds. I couldnt really tell but I believe that it is the lighter colored hit in the pic. I took another shot and it hit as well! It is the lowest shot on the target just below the orange. The two shots that hit at 1780 measured 10.1".
I measured the 4 shot group from 1300 yds and I was very excited to see that it was 4.9". My last 4 shot group at 1300 from last week measured 4.8". I am very happy with the consistency and accuracy of this load in my 338 LM.
I am learning a lot about the wind but I am also working on my form when I shoot. Breathing, shooting form, trigger pull and follow through is what I am trying to focus on and it is really helping me.
Critique whatever you see that I could be doing wrong. If you have any questions, I will answer them the best that I can.
