Hello. I've had good luck with the following load which is well within maximum load range. It'll group about an inch from my FAL @ 100 yards for 3 shots and then goes to about 1.5".
45.0 gr Winchester 748
Sierra 150 gr Matchking HP
Remington 9 1/2M primer
LOA ~ 2.76"
Velocity is around 2630 ft/sec.
