I've only really tested one powder and bullet combination. I have others, but saw no need so have never made time.
Norma brass, CCI BR primer, 28.0gr Benchmark (hodgdon max listed load), Hornady 32gr V-Max, seated to 2.250 (default length). It matches actual (not advertised) factory ammo speed in 24" barrel (4,000 fps) and...
shoots 1/2 MOA or less at 100 yards, about 3/4 MOA at 410 yards.
