This is more a reloading thread but I figured it would be more interesting in this forum.
I'm new to the PCC and was trying to develop a couple different things at the same time. I have been a USPSA and GSSF shooter for a few years and wanted to see what worked better for my PCC, a Palmetto AR9 I got last year. I'll eventually use it in USPSA PCC division, and I was developing a good 124gr carry load for my Glock 19, and a GSSF load for my 26. I also tested my USPSA Production load that I use in my Glock 34.
Data:
The 3.0gr Bullseye load was my standby for the last few years. Works great in the Glocks, and shot great in the PCC. (The "147gr" bullet actually weighs in about 149).
The Power Pistol load (and I can't remember the exact powder charge I used because I never wrote it down, I just loaded them somewhere near max) was to practice with my carry gun. The recoil didn't seem that much different with the rifle.
The 125gr was meant to mimic some carry ammo for my Glock 19, so I tried it with the PCC just to see what happened.
The load I was figuring out for my 26 for steel shooting, and to see if the 115 or 147 shot better in the PCC:
(damn flier)
Comparing the velocity:
I'm still not sure what I like better in terms of recoil, so I'll have to load a bunch of and practice some bill drills with the rifle
I worked the 115gr lower (all the way down to 3.0gr) just to see if the rifle would still work and it did. The Glock choked at 3.3gr. The rifle has functioned 100% with every single thing I've shot through it.

The suppressor is a Gemtech Multimount and I didn't do any of the test with it on.
