Best load I had for that weight in the vz-58 was 30.1 grains H-335, but with JSP. I shot 125 gr FMJ with 29 grains H-335 with good results.
Now using AA1680, I had a 123gr FMJ plinker load at 24 grains, a short range load chronoed at 2100 FPS. Not bad. 27 grains 1680 under a 123gr SP generated a decent all purpose round that steps out at 2300 FPS. Those are both chronoed out of an 18.5" CZ 527M barrel.
