JP GMR-13, all groups at 20 yards:
115 HAP, 6.2 AA #5 .625"
115 HAP 6.0 Power Pistol .50"
115 HAP 6.1 WSF .75"
115 HAP 6.2 3N37 .75"
OAL for all loads at 1.080"
I've loaded 95 grain Montana Gold JHP with 3.3 grains of WST. Excellent groups in a Sig P230. Shot POA/POI in a Glock 42, but was not the accuracy winner in that gun. Not bad, but others were better in the G42. No excess pressure signs.
I haven't tried any of these in 9mm, but have shot a bunch of them in various 357 Sig pistols with good results. 4.0 of N320 has worked well for me in 9mm with several 125 gr bullets. I'd also try 4.4 gr of Titegroup.
