Well today I was trying out IMR 7828 with Magnum primers behind Hornady 87gr V-Max. Ist load was 56grs MV was a 3,525 with in the 4s SD was less then 7 FPS Next load 56.5 MV 3,565 with SD of 12 FPS and 1/2MOA next load was 57.0 and MV was all over the place for 4 shots
1.3,678
2.3,619
3.3,568
4.3,583 But the group was a vertical string right at a 1/2MOA.
Then I tried Mag Pro with standard primer.
Max charge of the day was 60.5grs but the barrel had 30 rnds through it so accuracy was a nice round 3/4MOA group of 5 shots
1.3,622
2.3,617
3.3,622
43,632
5.3,644
Looks to me that Mag pro is my best load. Plus it was a hot day at the range. These loads will be my long range coyote ammo.
