I found my load notes.
Temp 85-90 degrees. Negligible wind. As stated previously, new Hornady brass, CCI200, COL 3.340", approx .045" from lands. I didn't look for accuracy nodes, since this is a 400 yd max shooter. I wanted powders that wouldn't lose a lot of velocity in cold temps. Vel average is 5 shots. I don't have the time to make this look pretty....
CFE 223 63gr 2760 64gr 2772 65gr 2837 66gr 2895 Accuracy got better as charges went up, and extreme spread shrank. Didn't try 67. 66 Looked pretty warm, and I didn't want to pull the trigger on them.
R-15 60gr 2743 61gr 2777 62gr 2836. 62 was tops I wanted to shoot. All were acceptable accuracy with low extreme spread.
H4895 58gr 2824 59gr 2886 60gr 2930 61gr 2971. Good extreme spread. Accuracy got better as charge increased. 61 pretty spicy. Shoot again 59-61.
TAC 61gr 2923 62gr 2936 63gr 2936. Accuracy not great. Maybe seat deeper. Low ES. Shoot again?
Shot the 4895 stuff again later, 59, 60, 61. 40 degrees, variable half-value wind, 5-20mph. 5 shots each. All velocities dropped approx 20 fps, 59-2862, 60-2910, 61-2951. I settled for 60 at 2910 because the 5 shot extreme spread was 26 fps over my Pro-Chrono from 10 feet. Accuracy in the wind created an elongated group, just over one and a quarter inches at exactly 100 yds for 5. I was trying to get the rig ready for hunting, so was looking for "good enough". I listed only shorthand conclusions in my notes for 59gr (NOT GOOD) and 61gr (NOT AS GOOD) I remember accuracy was acceptable for all, but 60 shot the best, and 61 just kept nagging at me as too much. There was zero bolt lift or primer issues, but it FELT like too much, and I didn't need the extra speed.
When I did the final sight-in with the 60 gr load, 3 went into just under an inch at 100.
Somewhere in my notes was 8208 test results, but I don't see them. They were poor for me, falling about 200 fps below Nosler's data, and hitting pressure at about 2700fps. I should do some more testing with TAC eventually, but I've already become attached to the H4895 load and feel confident in it. I've learned that my confidence in what I am shooting trumps my meticulously analyzed load and gun performance virtually every time when it comes to hunting and hitting animals.
