I use the Wolf SRM primers for everything. there are two, one for 5.56, and one a true Magnum. I use the 5.56 one. Harder cup takes the pressure better. With the same set up as you, the std CCI would almost always flatten. The mil primers or wolf ones never have.
I have used 3 loads for the 69's
The varget worked good in the old barrel, but the H4895 worked better. The new barrel will shoot 69's incredibly well with the H4895 Load. as a reference my .223 M700 5R shot them into just under a half inch this morning at 200 yds. they will shoot under a minute in the AR, but damn thats about as tight as I can hold, sure they would shoot better if I could. The RE15 was just as good, but I save that powder for the 75's and the .308.
24.7 of RE15 mentioned by Randy is hard to beat. We figured out the same load here in GA would shoot in just about anything. If I had to pick one load for XTC that would be it. If your gun won't shoot it, rebarrel it. Its that predictable.
My other favorite loads for your set up are
25.5 N150, .015 off the lands ( no its not too slow)
Varget and RE15 loads with the 80's were blowing primers for me. even with mild or std loads. The N150 gives me 2820 fps and zero pressure issues. Also RE15 wasn't good for 77's I would get pressure just when they started shooting good, but N140 gave me more speed and better accuracy way before pressure issues ( right about 24.8-25.0) and they were mild.
That 200 yd reduced MR-1 is nothin to f#@k with either.... Shot it once and it was the hardest target I ever shot.
Sir, the 200yd reduced target for the slow fire prone stage of the match is the MR-52. The aiming black is 11.79" diameter and the X and 10 ring are 1.79" and 3.79" diameter respectively. If the shooter/rifle combination are not capable of MOA accuracy it will be very difficult to "clean" this target. The same is true for the 100yd reduced target MR-31. JMHO, 7zero1.
