Loading 9mm at 1300fps

[918v]

I shoot 'production' class 9mm( 'minor' 130 power factor--1050'/sec with a 124gr bullet).

A friend shoots 9mm "MAJOR", and worked up to a load using compressed Silhouette Powder. His first run was 184PF or about 1600'/sec with a 115gr fmjrn bullet. Just a wee bit hot. Minimum PF for 9mm MAJOR is 165 or about 1450'/sec with a 115gr bullet.

He doesn't reuse his spent cases.

Why is it that your post survives but mine got deleted?

Power Pistol is more forgiving than Silhouette in terms of pressure. A 115 doing 1300 FPS using PP only generates 41000 PSI with is on the light side of +P+ and nowhere near MAJOR.

Is it because I referenced Clark. Is Clark a four letter word? It looks like a five letter word to me.

Those loads are truly incredible when you push a 115 grain bullet to 1300 your producing 959 foot pounds which i beleive speaks for the 9's possibilities as a personal defense gun

 

[cheygriz]

In most quality 9MM pistols, with 4 inches or more of barrel, 1300 FPS is easily attainable by CAREFULLY I repeat, CAREFULLY working up with AAC#7, HS-6, and Herco.

I've worked up to 1350, safely and backed down to 1300.

I like case life as one indicator of pressure. If I can load a case 3 or more times without the pocket loosening, I consider the load safe.

But I don't normally reload +P+ loaded cases after working up the load.

SAAMI spec is not a good indicator for the 9MM, because it was set for old military klunkers like the Glisenti. C.I.P is more appropriate, since it's the closer to the NATO standard.

MY Glock, Beretta, and several SIGs have fired thousands of +P+ 115/1300 rounds with no apparent damage or undue wear.

Umm... AveryJ, check your math. A 115gr bullet at 1300 fps is producing 431.5 ft-lbs of energy.

The formula I use for energy (and everyone seems to have their own...) is the velocity (in fps) squared (1300 x 1300), divided by 450,436, times the bullet weight in grains (x 115). The entire formula would be:

Velocity x Velocity ............................ 1300 x 1300
---------------------- X Bullet Weight => ----------------- X 115
7000 x 2 x 32.174 ............................... 450,436

In this equation, 7000 is the correction from grains to pounds, and 32.174 is acceleration due to gravity. In my experience, people use a different constant depending on what force they ascribe to gravity.

(Anyone who wants to correct these terms or numbers please feel free! I'm not a physicist, nor do I play one on TV...)

I shoot with an older gentleman who develops loads for Georgia Arms. He showed me some ammo they have called 355 Super. It's 9x19, but due to very high pressures they dare not mark it as "Luger". They had special brass made with the 355 Super marking.

It's used for "9 Major" in compensated 1911 guns. During our conversation he pointed to my SP-01 and said it would blow my gun up.

 

[ArchAngelCD]

RidgwayCO is correct, a 115gr bullet traveling at 1300 fps delivers 431.5 ft/lbs of energy, not 959 ft/lbs of energy.

Rfwobbly, the "355 Super" is a trademark load of Atlanta Arms and Ammo. It's simply a 9mm Major load.

Folks, it's really easy to load a 115gr to 1300+ fps safely. Load to the SAAMI max OAL of 1.170" and use Auto Comp. We load it for competitors and the pressure is at or below SAAMI +P pressure. I've reloaded the same brass loaded this way about 6 times and it still measured fine.

Go with a G22 and put a 357 Sig barrel in it Or just go 357 Sig imho...

Then load that one up to +P if you are looking for speed out of a 9mm same old story take a round and pistol and push them to the limits create a problem when none is really there

 

[LiveLife]

How about cut down 38 Super case to 9x19 length and shoot them out of Glock 22 with 9mm conversion barrel?

The extra metal around the chamber/barrel area should provide more pressure margin in addition to the 38 Super case?

 

[RhinoDefense]

The destructive point of a Glock 9mm barrel is in excess of 80,000 psi. No need to worry about chamber strength.

1300 fps is not a super hot load with 115's. The old VV book listed a 124 at 1295 fps using 3N37.

 

[Jim Watson]

VV lists a lot of stuff but I never got the advertised velocity.

 

[Blind Bat]

5.0gr of TG under a 90gr Sinterfire Frangible gets me an avg of 1428fps out of my G34.

Here ya go

90gr Gold Dot data to 1586 fps and other data for 115, 124, and 147

 

[jmorris]

1300fps is easy, my major 9 loads push 115 grain JHP's across the screens at over 1450 fps. There is quite a bit of data on brianenos.com loading 9mm to major PF.

 

[CSA 357]

im getting around 1250 fps with unique and 115 jhp

 

[JDGray]

6.4gr Power Pistol, 115gr Zero HPs, 1500fps

Sorry, shot from RRA 16" carbine

Thanks atblis, meant to include that tid bit of info!

 

[atblis]

6.4gr Power Pistol, 115gr Zero HPs, 1500fps

Huh? I've loaded the max listed by Alliant, which is 6.7 gr, and I didn't get anywhere near that. Is this out of a carbine?

At the time of which we speak, the early '60s, handgun ballistics were going through a time of great upheaval and revolutionary change.

Speer's first venture into expanding 9mm bullets involved their 125-grain soft-pointed roundnose. Their manual of the day recommended a certain charge of Herco which filled the case right to the brim and which was HEAVILY compressed by the 125RN bullet.....I had to actually dig the powder out of the case after pulling a bullet.

This load, according to the handbook, developed 1330fps from a standard 4" M39....with 125 grains, remember, not 115. I believe the quoted speed, because I chronoed the same load (yes, in 1970)in my Browning Hi-power. From its 4&5/8" barrel, it was traveling at an average of 1360 fps.

Note that these speeds are VERY close to the the highly-regarded .357 Magnum service load of that time, which was a 125 at just over 1300 from a 4" barrel,

....and then some folks claim that a 9mmP is a "mouse gun"! Not me, bro---that Browning with 14 rounds of Speer 125s was the equivalent of more than TWO fully-loaded S&W 19s, which rode in a lot of police holsters then.
