Pistol Power with 9mm major?

Where did you find Power Pistol? What weight bullets?

For Major, you accept going beyond SAAMI pressure specification?

I have seen 6.6-8.3gn being used with 121-125gn jacketed bullets, but that was with folks who carefully worked up the loads in pistols made for 9mm Major. It has been done.

The answer is it is suggested not to bother trying to run 9mm at Major speeds in stock gun, so I'm told. Powder Pistol is consistently the most accurate powder I have ever found for 9mm. The downside is flash and bang! Good luck..c[

Open STI's are made for 9mm major. It just seems like an unpopular powder for Open guns....

Then you are right! I did not catch that..I shoot Bullseye or for accuracy and was just surprises how accurate PP is in nine mill compared to all the others I've tried...

I have actually used power pistol with the BlueBullets in 147 gr.  (Weight of the bullet is actually 151gr.)  I tested the loads using my STI DVC Steel.  The more power the better on this gun.  It does run minor and major, so it is good for steel challenge, and USPSA open division.

 

I will post data since there is few using these components......use at your own risk!

Loads are as follows:

151gr Blue LRN

5.9 gr power pistol

cci 500

C.O.L. 1.160

mixed brass

 

I tested with an 8 shot group.          AVG VELOCITY 1117 F.P.S.

1100                                                  P.F.= 168

1115

1106

1095

1141

1117

1135

1131

 

Next group same specs except 6.0 gr. power pistol.

1123                                              AVG VELOCITY 1136 F.P.S.

1128                                                P.F.=171

1123

1173

1134

1146

1128

1135

 

Last group I made 9..   6.1 gr. power pistol

1204                                            AVG VELOCITY 1164 F.P.S.

1165                                               P.F.=175

1147

1178

1140

1175

1180

1124

1170

 

The last load at 6.1 gr. felt the smoothest.  No primer flattening, case bulging or other pressure signs.  Good luck.
