Well, here is what I came up with today. Not as tight as I was hoping for.
I shot four rounds at 1475 yards. They were going a little faster than the 1273yard shot because the brass weight was 2 grains more today. The first one went right over the top, and the next three after I came down 1 MOA grouped. The group size was 20.5"
I tried again about an hour later, the wind changed directions and was blowing 5 mph so I redid my calcs. and this is the best I did with three shots.
One high left on target, one in the dirt to the left in the painted circle, and who knows about the third. I don't think I was reading the wind very good there. My ammo was not as consistent today either, I was averaging about 3120fps. Low was 3116 high was 3128, with one @ 3183! Don't know what happened there? I guess the average was higher than 3120. The first three might still be good enough for elk at that range, but I think I will keep on practicing.
