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.
You can avoid having to lube cases. Run brass thru a .40 S&W carbide sizer first, then thru the .357 sig sizer. No lube required. I also use a Redding taper crimp die and have no setback issues. I like Power Pistol and Longshot for 1350 to 1375 fps loads. N350 also shows promise. 800x is great for velocity and accuracy, but as others have noted, it meters about as well as tortilla chips.
180 grain Zero JHP or Speer TMJ pulls with 5.4 grains of Silhouette, Win SP primers at 1.130 has shot extremely well in several .40 Glocks with factory barrels. Sub 2" at 20 yards.
For me, the Bayou 147’s are more accurate. Still trying to find "the" load for the 135 grain ones. I've tried a number of ones posted here but not seeing accuracy equal to the heavier bullets.
In my 9L, the best 124 gr load was 4.0 N320 with a Hornady FMJ FP. It went 1.5" at 20 yds. The best load in the gun to date is 4.0 WSF with a147 Zero FMJ - 1" group at 20 yds. Same load with a Hornady FMJRN did 1.25". Three quarters of the loads it will shoot 2" or better (16) are with 147 gr bullets. The above 124 gr load is the only one that shoots under 2" for me.
5.4 grains of Silhouette with a 180 gr jacketed bullet has been the most accurate load for me in several Glocks, with 1.0 to 1.5 inch groups at 20 yds off the bench. Unfortunately, it doesn't make major, approx 150 PF.
