Power Pistol 9mm loads

[Pauley, Ralph]

So looking at the load data for 9mm using Alliant Power Pistol.   First I’m not trying to shoot X’s at 50yd, just plinking and or action pistol stuff all inside 25yd.

 

Load suggestion from Alliant for a 115 JHP is 6.7gr of Power Pistol.  Lee manual list min load at 6.2 and max at 6.7gr.

Well I loaded up some 6.5~6.6gr and took it to the range. 

Youza, is that hot.  Accurate but quite zippy and recoil definitely strong and snappy.  Primers showed evidence of quite a bit of flattening and flow back.  I didn’t measure muzzle velocity but it was supersonic.

 

Gulp,  Ah, well what happens if I down load it. 

I made about 20 each of 6.1, 5.7, 5.4, and 5.1

I didn’t expect the 5.1 or the 5.4 to even cycle a Glock G19 & G34

Well surprise, the 6.1 was still very snappy but accurate.

Then went straight to the 5.1 load to verify it wouldn’t cycle. 

Surprise, it cycled both the G34 and the G19.  Actually quite well and kicked the empties about 3ft right and behind me like a well-tuned wad gun.

More bad news, The group was great.  17 of 21 shots in the black, 9/10 ring of 25yd target.  Off hand (2-Hand hold) at 25yd. Using iron sights in the wind.  With a fat old guy wobbl’n round shoot’n ‘em.  (me)  Hmmmmm sez I.  Don’t make no sense.

 

So I went ahead and shot the other loads, 5.4 and 5.7 their groups were not as good as the 6.1 or the 5.1gr.

I’m speculating here.  I think the light load may be departing the barrel subsonic.  The 5.4 & 5.7 are arriving at the target sub sonic but leave the muzzle above the speed of sound.  (possibly only the G34, G19 may not have been super)  Then the hot loads stayed supersonic the entire distance. 

 

I must say the lighter loads accuracy surprised me and the fact they cycled the pistols.  I didn’t try it in any other pistol besides the G34 and the G19.  I should test all before making a large batch.  Want to make sure it cycles the carbine as well.  Those hot loads 6.6 make the carbine sting.

 

So chew on that, should I make up a bunch of the lighter powder puff loads or the HOT stuff?  Does GSSF require a minimum power factor?

A long time ago after posting some test results. Someone said that JHP bullets (this was for 45ACP) have 2 speeds where they are accurate. Above, below and in between they are less accurate. Perhaps it's true for 9mm also. I've seen some evidence this is true, but never tested enough to confirm.

I should 5.1 of power pistol for both distinguished matches with the M9 and centerfire matches with a 9 mm 1911. Both extremely accurate. The power curve and speed matches up to the Atlanta arms match 9 mm ammo.

Please elaborate, which bullet, length, crimp, primer, MV, etc.  How did you determine the "power curve?"
Here are the published specifications of AA 9mm Match:

Interesting,  They are staying subsonic the entire trip.

I'm thinking about trying my G19 in an EIC match. I ordered a Ghost trigger kit to smooth things out. 5.1gns of Power Pistol has worked great with 122gn lead bullets, but I'm not sure about Rainiers. Is there a body of knowledge out there regarding GLOCKS and EIC matches?

[R Dan Pauley]

I know the .45 glocks can be very accurate but think the 9mm may not make it to long line accuracy we need. Keep us posted if you do testing at 50yd.

I took a G17 to the CMP Games in OK a few years ago, just because they
had a match for it, with no single actions allowed in that match*. I
shot it with plain old American Eagle 115 FMJ.

(*Arguments about what kind of action a Glock has go here.)

The police pistol match, or whatever they called it, was all at 25
yards. I took a silver medal. The funny part is that I completely
choked on the service pistol match the same day. :)

Test what you've got, compare to your other EIC efforts, and decide
for yourself. It's all just fun.

BTW, I have about 48 EIC points, all with 45 ball, but have yet to win
a hard leg.

I had very good accuracy using 6.0 Power Pistol, 115 Gr. Hornady FMJ bullet in my Beretta with KKM Barrel. They are a bit snappy though!

I currently use 5.0 N340, Sierra 8115 Bullet in the same gun for Service Pistol. Not as snappy as the aforementioned Power Pistol locd

Has anyone tried the new Alliant Sport Pistol?

What kind of trigger did you end up with, with the Ghost?  Which model of Ghost trigger did you get?  I looked at their website, and they offer lots of choices.  Hard to decide.    I would recommend jacketed bullets; the Hornady 115 gr JHP, the Nosler 115 gr JHP, and the Sierra 8115 FMJ have been mentioned by very knowledgeable folks on this list.  Glocks with stock factory barrels have been know to blow apart, due to shooting lead bullets.  I have seen 2 tupperware pistols go KABOOM, one was a Glock, the other was an XD, both were .40S&W, but in these 2 cases, both were using jacketed bullets.  Neither person was very experienced in reloading, and I suspect both were double charges.  A customer at the same indoor range did blow up his Glock with lead bullet reloads, due to lead build up in the factory bbl.  Don’t remember the caliber.      --Roe Hicks,  Haysville KS
