I've been shooting Frontier 180 gr FP Restrike out of my P16-40 with good results.
I've also tried 165gr RNFP (non restrike) but have not found an accurate load yet. I think that the restrike-process does make a difference. The 165ers were about your second picture, or what it would translate to on 25 meters, and the 180gr FP Restrike are at least as good as your first pic. Sub 3" groups at 25 meters and I could be responsible for at least one of those inches
Not sure if they are "very accurate" but they are good enough for me for IPSC, 25yd PPC and 25 meter target shooting. (Not tried 50yd yet)
