    I have a couple of loading manuals, the latest Speer and and older Accurate manual and neither has information for 9mm +P loads. Can someone post some +P loads, or point me in the direction of a page showing a couple? Thanks....

    I would be extremely careful trying to load +P loads. They border on being unsafe, use special powders and crimping techniques, and are not easily duplicated by handloaders. There are old reloaders and there are bold reloaders, there are no old bold reloaders!:uhoh:

    There are only two kinds of Triple riders. "The Quick And The Dead"

    We now return you to your previously scheduled program. :neener:

    Ya know Walkalong...He's right.:D There is no listing in any of my manuals showing a +P load. BUT...I did chronograph fifty Remington 115 grain JHP +P factory a few years back and I still have the data. Just for starters the velocity for a Remington 115 grain JHP +P is 1170 fps from a 3.3 inch barrel. More loads then you can count in my manuals list 9mmX19 115 grain JHP at more then 1200 fps. I would guess you could say that a maximum load is the same as a +P factory.

    I do, however, agree with everyone that I would be very careful working up to those levels. I have been using 4.6 to 4.8 grains of W-231 under a 115 grain JHP (Winchester) and a WSP primer and getting almost 1100 fps from a 3.3inch barrel. I believe that might constitute a +P loading...Please...If you use this load. Start at 4.3 grains of W-231 and work up carefully.

    With all that being said. Yes. They are +P loads at the maximum charge levels and must be delt with accordingly...

    References: Lyman 48th edition ( maximum of 4.9); Sierra Vth edition 2nd printing (maximum of 5.3); Winchester load data (maximum of 4.8) and my own load data log (maximum of 4.8). All these maximum powder charges are for 115 grain JHP bullet. Quite a wide range of differences...

    If you want some shock and awe, get a can of Power Pistol. Handbook loads with it will give higher velocity than most, accompanied by a lot of flash and blast that will let everybody know you are shooting powerful bullets.

    9mm major load data

    STAFF EDIT: LINK DELETED

    The link given is to one handloader's efforts to make 9x19mm into a MAJOR POWER CARTRIDGE. The majority of loads given are WELL inexcess of maximum loads published on powder manufacturers' sites and in recognized loading manuals. Further, the writer tested his loads in a specially set up pistol, supposedly modified to handle high pressure loads.

    This type loading information has no place on the THR H&R Forum unless labeled with BOLD FACED WARNINGS, and even then I have major misgivings.

    Mtdew gets the benefit of a doubt, that he's just trying to be helpful. Don't anyone else post that link.

    The reason I was looking is because my nephew, who is a NY City cop, gave me a box of 9mm +P to use and I really liked them. He's issued 9mm +P ammo. It's Speer GoldDot, 124g HP. I was wondering if I could duplicate this but none of my loading manuals carry the formula.
    Thanks....

    9mm SAAMI max average is 35,000 psi
    9mm+P SAAMI max average is 38,500 psi

    That 10% increase in pressure, according to my Quickload program, can be had with a 3% increase in powder.

    I don't think you will notice the difference.

    I have a case of Hirtenberger 9mm +P+ that seems wimpy to me.

    Edition 2 of the Vihtavuori reloading manual had loads that would match Speer Gold Dot 124gr +P, i.e. a 124gr at 1250-1325fps.

    I have loaded the 124gr Gold Dots to 1280 or a bit more with VV 3N37, per the above guidance from the VV book.

    Definately NOT something I would do. Over use of +P ammo is not something ya want to do. :evil:

    Biggest problem, 1/10gr over could cause a K-BOOM!

    Power Pistol would be a good place to start for loading 9mm +P, it is the same powder that is used to load 9mm NATO spec ammunition. If you follow the published data and use sound loading procedures, it will yield +P equivalent loads.

    Just my .02,

    Mind you Mugsie. +P and +P+ are hard on handguns if fed a steady diet of these. Best to practice and fun shoot with lower powder charges and save these for the real thing...

    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.

    Well Nelson...That's why we can hand load. So we can have our cake and eat it too. (Hopefully not with gun parts in it:eek: ).

    That is supposed to be the powder for full loads in the 9MM. How does it do in .40 or .45? Thanks.

    No idea, sorry. For anything that I load in bulk for pistol these days, I am using Titegroup (which is NOT a good choice for full house 9x19).

    According to QuickLoad, 3N37 should be OK for 40SW, but is probably too slow for 45ACP.

    Thanks. I've tried N310, N320, N330, & N340. What the heck. I might try it. Is it denser than these others?

    My experience with 3N37 is that it leaves granules in the gun unless it burns at high pressure.

    Thanks. Sounds like it is out for the .45

    Power Pistol

    I've used up to 6.4gr Power Pistol with a 124gr FMJ bullet. PP is pretty hot compared to other loads I've used. It's great with 9mm and .40 S&W too.

    Yeah, I just assume my carry load is +P because of the velocity I get from it. It pushes a 115 grain Hornady XTP JHP to 1260 out of a 3" barrel, 1340 out of a 4.5". I load it in commercial brass. Case volume is less on most military stuff and pressures could be higher. I worked up to it watching for any case swelling at the feed ramp in particular. It is a safe load in my two guns, a Ruger P85 and a Kel Tec P11. It is the top load for Unique in my Speer No.11 manual, 6.4 grains. I've shot probably 1000 rounds of this stuff in four different guns over the years and never had a problem. I don't feed a constant diet of it to even my Ruger, but especially my KT. It's eaten a couple hundred rounds of it ot of the 10K+ it's fired in its lifetime. I carry it with that load. When the loads get old enough I begin to wonder about 'em, I'll fire 'em up in my Ruger. It's a tough gun.

    Anyway, at 410 ft lbs out of a Kel Tec P11, we're in snubby .357 magnum territory with a lot less flash bang and a lot more controllable recoil with a lot more capacity than a five shot revolver. It is quite a good little pocket combination IMHO. Beats the heck out of .380, anyway.:D

    I know a couple load book fundamentalists that value their old "Vihtavuori One" book with the most powerful 9mm loads permitted by load books.

    3N37 Costs more.
    3N37 makes less muzzle flash.

    9x19mm 3N37 147 gr book load from Vihtavuori may make the majors and Power Pistol book loads from Alliant can't.

    But in a load work up, I can get more power with Power Pistol than I can from 3N37.
