I’ve shot thousands of 9mm FMJ RN through multiple guns. I do a lot of competitive USPSA.
For my PCC load, I use 4.4gr of Sport Pistol under a 115 @1.125”. This gets me right around 140PF which id about 1200fps out of a 16” barrel
I also use these for shooting Open division. I used 10.4gr of Shooters World Major Pistol under a 115fmj rn @ 1.180” and a small rifle primer. This gets me about 1500fps out of a 5” barrel with 2 3/16” ports. I do NOT recommend this recipe for the average shooter/gun unless you know what you’re doing…
Another powder I use is HS6. 8.8gr at 1.180” again. Makes major power factor no problem!
