Did a ladder load development today at 300 yards. Had full value wind at around 8mph, but that speed was not constant. The vertical on the top group was right at 1/2". That was pleasing. Steve and I expected the wind to give us fits horizontally.
After some more loading I took the top four numbers and loaded 8 of each ( 5 for group and 3 for getting some MV info. Wind had changed, was stronger with more gusting. Shot again at 300 yards. Best group had four shots right at 1/4MOA with one going higher. On all four groups the vertical was higher than when doing the ladder in the morning. That was to be expected, but I still wanted better, even though the conditions were not in my favor.
105 hybrid @ 2888 fps. Took some of the other rounds (9 in all) and shot at 400 yards and was able to put several shots on top of each other on steel, which is always gratifying. Then I went out to 500 yards with fire forming loads, but soon had to give up becasue of excessive wind and rain.
Will load some more of my chosen load and adjust the OAL 10 thou longer and then 10 thou less to see if I can tighten things up a bit more.
