===========
My friend told me that WGS had Ramshot "COMPETITION" pistol powder last week. I never used that before but it is a really fast pistol powder.
Looks like a good choice for 45acp. I dunno about 9mm though. Maybe too fast.
Once again, thanks for the heads up on this powder.  Have not tried it yet in 9mm yet, (but I will as soon as my 9 Pro slide gets back from S&W...again), so hopefully I don't get the  :stopjack: sign dropped as this is a 9mm thread, but, just wanted to post that in .40 minor and major, this stuff works really well.  Single digit SD in minor with greater velocity than N320, but with less muzzle rise.  SD in the low teens for major, about the same feel, comparable to N320.  Couldn't believe it, especially the minor load.  Meters well, but it does seem to take a little longer to settle down with consistent drops when starting with an empty powder hopper. 
On a side note, both minor and major loads with moly coated bullets were super clean.  Almost no smoke, and after 300 or so so rounds, was almost as clean as when using CMJ bullets with N320. 
.45 is next, hopefully the results will be like what I've found in .40.

That is useful information. Thanks for the mini review.

Here is another alternative powder: Winchester WST.shotgun powder.
As the supply of normal handgun powder is getting thin, if you have some of this powder you can try this recipe in the 9mm.
However, I do not recommend this unless you are really desperate.
9mm
124 gr Xtreme PHP
5.2 gr. WST
LOA=1.12"
TC=0.374"
Primer=Fed (GM100 for this test)
Case= FC
Test gun=sw3913/ 3.5" bbl.
AV=1035
SD=23

You can expect velocity of around 1030 to 1070 depending on your bbl.
Accuracy at 25 yds was actually pretty good... see the pic-squares are 1"
Velocity deviation was not so hot.
I would not deviate too much from 5.2 gr.--the pressure curve seems weird.
Large variation in charge weight did not affect velocity as much as predicted.
