Not bad, pretty good. But on fast side for use in 5.56 for sure. This is 50 yards. 2 groups at bottom are about 1 MOA, or about 1/2 inch at 50 yards.
Of note, the upper right load, labeled "test" is probably the best all around load I have ever found in 5.56. Benchmark 25.0 grains using 55 grain Sierra BlitzKing. I shot it here for control group. I don't recommend H322 for 223, you can do better with Benchmark, or various other, slightly slower burning powders. H322 is like VVN130 for example in burn rate. Maybe good for 40-50 grain bullets at most.
