I just recently did a load development using H335 and 55 gr FMJBT bullets in .223. COL was 2.200”. These are the results:
23.5 gr 2762 fps
24.0 gr 2817 fps
24.5 gr 2882 fps
25.0 gr 2941 fps
25.5 gr 2977 fps
26.0 gr 3032 fps
26.5 gr 3081 fps
To my surprise the best accuracy and grouping was attained with the 23.5 gr load.
