These are some videos a friend made. He helped me with my load development as I had no clue what I was doing.
After doing the above, and then going through a ladder test, we found a couple of loads that would work. We then proceeded to do a 3 shot test of each of the loads, as that was all we had left. We ended up with the following.
40.8 Grains with a 1.3 Inch Vertical Spread at 600 Yards with a 3.9 Inch Horizontal Spread.
41.1 Grains with a 1.2 Inch Vertical Spread at 600 Yards with an 11.4 Inch Horizontal Spread.
We were not concerned with horizontal spread as that was all wind, since it was windy.
