I have had good luck with 124 gr plated and/or jacked bullets and 4.2 gr of Beye with CCI primer and any case. Gets out the bbl of my G17's around 1050-1075 fps. Have used it in plate matches and GSSF matches.
I'm sure other powders will work as well or better but I just like the way Bullseye meters and an 8 lb. jug goes a long way.
