Looking for 9mm +P loads

[Walkalong]

Power Pistol is 40% Nitro content. Maybe thats why. I dunno. I think 3N37 is single base. I know N310 thru N340 are.

What about primers?

I noticed MTDew listed SP magnum, SP, SR, and SR magnum primers in those 9mm +p loads. Were those typos or is someone actually loading 9mm with SPM and SR primers. I have a gazillion Wolf SRP that I would love to be able to load 9mm. I recently purchase a Loadmaster progressive press and used up all of my SP primers. I have had SP primers on back order for 3 months and everyone just keeps pushing the due date back. I am getting ready with my I told you so. If I were a little commie and I wanted to limit Americans access to ammo, thus firearms, I would buy all of the primers. All of the primers used in every category of ammo for all non-military/police use everywhere in the world would only cost $50 million/year. That is chump change to a US President and he doesn't need to change one law to do that. Hope and change... Yes we can...
I can and do make bullets. I can make casings. I can even make powder. I cannot manufacture primers.

Good info - as a big 9mm fan, I'm honestly really pleasantly surprised that there have been no smart-@ss responses like...

"...if you really want a +P load, you need to step up to .357 Sig, .40 S&W, etc., etc., etc..."

Cool.

The Alliant reloaders guide recomments 6.7 grains of Power Pistol for 115gr 9mm.

Since I'm loading Rainier Ballistics plated 115gr RN bullets (which they recommend loading to 10% under recommended standard metal jacketed bullets) I am starting my testing with 6.0 grains of Power Pistol.

Am I playing with fire??

It seems I'm also over crimping a bit (0.007" indent into the bullet after pulled) which increases the worry that I'm turning out little hand grenades rather than good reloads - tomorrow I hit the range for the first time with my 9mm loads.

I have loaded 9mm P with small rifle primers. Reliable ignition and no "pressure signs" whatever that might be at sub-maximum loads.

 

[Marlin 45 carbine]

many of these loads are into .357mag velocitys so this states the 9mm Para is a good s-d choice.

 

[Claude Clay]

real good question and lots of great info resulted.

124 gr Rainer with 6.6 of Power pistol and a strong crimp replicates a 124 gr +P Cor-Bon. this powder gives the same recoil feel and the crono reads within 30fps.
caution about everything esp the crimp--lighten it and the 'feel' aint right.
FM-793, this is a entry level 357 SIG round and i do fire them in my sig bbl. gun functions fine as the case length is long enough that as it ballons it contacts the shoulder area in the chamber. no pressure signs and the POI is a bit above a 357 Sig round.

I suspect 6.0 grains PP *could* actually prove a good load with the 115 plated bullet...I've shot that bullet at this level with no problem. That said, the caveat here is that you cannot over-crimp them and retain accuracy and it sounds like you might be. I'd recomment seating them 1.14 or longer with your load and reducing the crimp to only remove the bell (flaring) of the case. This will likely be ..3765/3775.

I like to load 115 gr. RN bullets to 1.130". 6.0 gr. Power Pistol should be a great load with a 115 gr. bullets. Power Pistol is one of my favorite powders especially in 9mm.

IIRC 6.2 gr of PP yielded 1275 fps out of my G34.

I scrapped the 100 or so rounds that I had that aggressive crimp on and started over. With an OAL of 1.150", 6 grains of PP, a proper crimp and the 115gr plated bullets the loads worked great and were very accurate.

The only drawback is there was LOTS of residue in the barrel even after just 40 rounds or so - and I get quite the fireball with each shot...

 

[D. Manley]

I don't shoot P.P. much since most shooting is indoors and that fireball you mentioned can be annoying. I've not noticed it being particularly dirty though and IME, it cleans up pretty well with sufficient pressure. Since you're shooting plated you may not be able to put enough "go dirt" under them to get pressure up but you might want to think about going to 6.2 grains and see if it helps. IIRC, this was my most accurate load with 115 jacketed. Even 6.2 should be OK under the plated and hopefully, the fireball should'nt be much bigger...

Bullseye is a good powder for 9mm +P loads. I used to use Green Dot, but Bullseye gives a lot higher velocity for the same or lower pressure. Shouldn't give you a lot of muzzle flash either (I dunno, I've only shot it outdoors in daylight.) I load 135 grain cast bullets to about 1200 fps.

WSF is a great powder; supposed to be good in 9mm but I haven't gotten around to trying that yet. The burn rate is the same as Herco, but it's denser and measures better (Herco is too fluffy to use in 9mm hot loads, just like Blue Dot)

My range report 2009-02-06

Kel-Tec PF9 3.1" barrel
1) 124 gr FN Honady bullets and 10 gr Power Pistol. 1336 fps.
2)100 gr Hirtenberger +P+ 1275 fps

Alliant max load 4" barrel, 124 gr, Power Pistol 6.4 gr., 1,157 fps

When I shoot 11 gr Power Pistol 158 gr in a 9mm [over sized throat and resized loaded ammo], the recoil hurts my hand for an hour from shooting 3 shots.

I guess I'm mystified why any one would want to load high pressure rounds for any pistol caliber. I only use handloads in a pistol for practice, and I don't see any reason to beat up gun or shooter for practice.

I think it has to do with personal protection loads. +P are issue loads for the LEO apparently. I bought a box of the new Winchester +P man stoppers at Wallyworld the other day. Tax and all was $1.00/round. Heretofore I had never had the first thought about reloading 9mm. Now I am beginning to wonder.
