    @CCT125US - I’ve had to do a similar thing for my 9x19s. The tightest chamber among them is in the P99c, so I use that barrel for the plunk test when I’m working up loads. The Berettas and CZs don’t seem to mind.

    My current load is 3.6 grains of 231 with a 147 grain coated roundhouse at 1.14 oal which chronos right around 900 fps in a P30SK and around 920 in a P99, with very little deviation. Pretty accurate and clean, and close enough to full power carry ammo for quality practice sessions without beating on the gun unnecessarily. I had been using flatpoints but switched to roundhouse as both the P30SK and the P99 required the flatpoints to be seated deeper than I liked. Walter PPS didn't care though, go figure. I like the 147s both for recoil characteristics and for the fact that they impact a little higher and I like my point of impact to be at or above the top of the front sight rather than below it.

    I finally got out the chronograph that had been gathering dust in the garage. Before I began my journey as a professional D class shooter in USPSA, I never really cared about power factors.

    Much to my surprise the loads I had been using for the last 4 pounds of a proprietary powder blend all chronoed above the base line for minor power factor. Unfortunately one of my PCC's likes shorter COAL's and I ran out of my gift powder.

    This is my first shot with this so tell me if something looks bad.

    Bullet: RMR 124gr JHP Powder: WinClean 244 Primer: CCI #500 COAL: 1.075 UNLESS NOTED 10 SHOT STRINGS

    3.3gr WinClean 244 SIG P320 X5 Legion 14 shot string
    HIGH: 946 Low: 874 Extreme Spread: 72 fps
    AVE: 902.8 SD: 19.39

    3.6gr WinClean 244 SIG P320 X5 Legion
    HIGH: 1055 Low: 993 Extreme Spread: 62 fps
    AVE: 1,010.3 SD: 17.748

    3.8gr WinClean 244 SIG P320 X5 Legion
    HIGH: 1065 Low: 993 Extreme Spread: 72 fps
    AVE: 1,029.3 SD: 17.83

    3.8gr WinClean 244 GLOCK 17
    HIGH: 1073 Low: 1033 Extreme Spread: 40 fps
    AVE: 1,052.1 SD: 10.16 PF: 130.46

    4.0gr WinClean 244 SIG P320 X5 Legion
    HIGH: 1076 Low: 1048 Extreme Spread: 28 fps (NINE SHOT STRING)
    AVE: 1,063.8 SD: 9.79 PF: 131.9

    4.0gr WinClean 244 GLOCK 17
    HIGH: 1118 Low: 1069 Extreme Spread: 49 fps
    AVE: 1,087.6 SD: 11.93 PF: 134.8

    I was shooting through the chrono at a USPSA torso with a 4 inch black sticker for a bullseye. 3.8 and 4.0 shot best in the Legion, group sizes were meh because I have presbyopia and if the front sight is clear, well nothing else is - they were 60% in the bull the rest circling. The Glock 17 has an RMR on it - one raggedy hole.

    Shooting one right after the other really accentuates the differences in weight, the Glock was a little snappy at 4.0, the Sig just kinda sits there.

    That's pretty cool. I have a bunch of those that I bought at SHOT when they came out, and always wondered how they would perform

    The SDs tightened up at 3.8 and 4 grains, and you said the accuracy did too. If it were me, I’d settle on 4 grains and call it good. As a general rule, you want to be at least 5 over power factor to account for differences in chronos and temperature changes.

    Thanks, that's what I did. I didn't shot the RMR Glock until 3.8 and 4.0 though. I settled on 4.0.

    The Berrys hybrids over expand in just about every test I’ve seen
    Only at low velocities can you count on adequate penetration
    The 147s should be ok but I loaded my 124s down to about 1050 FPS in order to keep them from over expanding

    Good to know. I bought these as a backup to my carry load, 124+P Gold Dots, in case I ever ran out and could not get replacements. Back then Gold Dots were unobtainable in bullet form due to demand but later was able to get some.

    Just some more data points for Alliant Sport Pistol:

    147gr Blue Bullet TC 0.3555 loaded to 1.14 OAL using mixed brass"

    Crimped to just remove bell

    10-15 discard rounds loaded in between powder adjustments

    CCI Small Pistol Primer

    Sig X-five Legion

    70 degrees F

    Average FPS of 10 shots

    Loaded on Dillon Super 1050 with powder baffle, SSI funnel and micrometer adjuster

    Velocity measured via magnetospeed V3



    3.0gr=860fps S-D:7.0 PF:125

    3.1gr=882fps S-D:9.1 PF:130

    3.2gr=897fps S-D:6.7 PF:132

    3.3gr=926fps S-D:9.8 PF:136

    3.4gr=939fps S-D:14.7 PF:138

    Overall very satisfied with this powder. It's pretty clean, doesn't heat the gun up a whole lot, not smoky, meters very well, and seems to burn pretty consistently.

    Presuming that 3.2 grain load gives good accuracy, it looks like a winner. 132 PF is enough "cushion" for the chrono stage that I'd be comfortable, presumably it's quite soft shooting, and 6.7 SD is nice and consistent.
