mine aren't green tip, but...
I have been buying the 62 gr. FMJSCBT SS109 from Wideners and have had zero problems with using standard published data. Don't have my references here with me but IIRC for H-335 the range was 23.0-25.0 grains; I ran the gamut in 0.2 gr increments and settled on 24 gr just to avoid wear and tear on the rifle. I have however noted that I must seat them to where the canalure is almost inside the neck to comply with the magazine length.
