Powder for 9mm SHTF ammo?
« on: December 31, 2016, 10:12:30 AM »
Any one else keep a stash of 9mm JHP ammo for SHTF purposes?

Many years ago, I worked up ammo loads with the then new Winchester Super Field (WSF) powder.  I found this powder worked well for this showing good velocities with a low flash signature.  My standard load of 5.1 gr WSF with a 124/5 gr JHP worked well even in short barrel concealed carry guns. (test gun is a S&W Shield)

Lately, I've been experimenting with some of the newer powders out there to see if their is anything better.  I've gotten similar results with BE-86 but Longshot was a bust showing lower velocities with more muzzle flash and blast.

Anyone have any other suggestions for powders to try?  So far I've also tried Blue Dot, #7, Herco, and WAP. (now known as Silhouette)

Hey Jeff have you tried CFE Pistol and then there is Winchester AutoComp
Speer - Brass (this was what I found in the UW +P+ loads)
115gr Nosler JHP  +P+ over 6.6 grains AutoComp was rated at 1500 fps / 574 ft. lbs
124 gr Nosler JHP +P+ over 6.4 grains AutoComp was rated at 1300 fps / 465 ft. lbs
147gr Speer Gold Dot JHP +P+ over 6.4 grains AutoComp was rated at 1250 fps / 509 ft. lbs

Thanks Wade, I haven't tried either of those yet but I was thinking of getting some Autocomp to try as I know a few USPSA open division shooters that use it in their Major 9 loads.

I was also thinking of trying the new Winchester 572 (replacement for the discontinued HS-7?) and perhaps the new IMR Blue when it becomes available.  (I wanted to try them both in the 10mm anyway)

Anyone else have any data or experience they'd care to share?

6.9 grains of Vit 3N38 over a 147g Gold Dot is what I use. It will make 165PF out of my Bar-Sto barreled Hi-Power and has a very low flash signature.

Thanks spencerhut.

I remember testing some 3N37 right after team USA got their asses handed to them at the IPSC world shoot back in 1990 by just about all the European shooters using 9mm's loaded to the old major PF.

I've always been impressed with the performance of the VV line of powders.  I've shot several guns loaded with them while working the chrono stage at some major matches.  About the only negative thing I can say about their performance is they tend to be reverse temperature sensitive.  And that's not really a negative, just something to be aware of.

The only thing that's kept me away from the VV line the the cost and spotty availability.  I may have to re-evaluate that.

I just ran some 572 loads over the chrono along with a few other powders for comparison.

These loads are all above max or have no book load to begin with. They proved safe in my gun but do not attempt to replicate without careful load workups!

Test Gun: Glock 17L, 6.5" lw threaded barrel throated for .357 mag wfn bullets. LW compensator installed, 24lb wolff recoil spring and steel guide rod.

CCI SP primers used for all loads, and loads were loaded in CCI blazer once fired brass.

7.0g 572, 125gr xtreme plated fn (.358) @ 1.150" = 1349fps (.389 case head)
7.0g longshot, 125gr xtreme plated fn (.358) @ 1.150" = 1392fps (.390 case head)

5.7g 572, 158gr swc (.358) @ 1.150" = 1250fps (.390 case head)
5.7g 800x, 158gr swc (.358) @ 1.150" = 1162fps (.389 case head)

5.7g 572, 147gr PC cast FP (.357) @ 1.150" = 1270fps (.390 case head)
5.7g 800x, 147gr PC cast FP (.357) @ 1.150" = 1134fps (.388 case head)
5.1g autocomp, 147gr PC cast FP (.357) @ 1.150" = 1204fps (.390 case head)

I've run loads up to .392 case head expansion in this barrel so for .390 being the max seen here these were very impressive numbers, especially for the 158gr swc. FYI factory 115 grain standard white box has .388 case heads when measured after firing.

572 really woke up with the heavier bullets but that's not surprising since its very close to blue dot in burn rate. 572 is another loud one, similar to longshot and should make for some impressive numbers in the larger rounds as well.
