Shot my first rounds today. No load development just trying the only factory load I have (Hornady AG) and my AR pet loads. All were 3 shot groups at 100 yds.....
Started off with 123 Hornady American Gunner.
2429 FPS, ES 28 and SD 14.
.6" group.
Then shot some of my AR pet loads,
123 SST, 27.2 8208, 2474 FPS, ES 31, SD 18.
Had one shot that was 2400 fps that opened the group up. I did not count this in my ES, SD or average FPS because there had to be something wrong with the load. It was 1.4" group with it and not counting it the group was a .6" group. Would have brought my ES up past 80.
This is a hot load for the RAP. Observed some shinny extractor marks. I'm going to have to reduce this. Will try 27 grains and see how it does.
120 Gold Dot, Wolf Steel case and Wolf primer. 29.2 grains of AA2520.
2493 FPS, ES 14, SD 7.4
1.24" group.
Fastest load of the day and looked promising. I just purchased a new 1lb of AA2520 (made in US) and will do some load development once I find some 120 GD's somewhere.
129 Nosler ABLR, 26.9 ARComp (5 shot).
2404 fps, ES 60, SD 26.
2" group
Not so good for this load. This is the best shooting load in my 18" AR.
