I've had good luck with xtreme plated. I use 115gr 9's, 230 gr 45, and 180 gr 40.
However, I just picked up a new blaster, and the gentleman who sold it to me had some 165 blue bullets to shoot. They were under major PF, but VERY accurate out of my new gun (6" 40.) I've ordered a few sample packs from blue bullets to try.
