Wow, shot a 9mm MAJOR last night!...

[zipper046]

A local shooter had his Open gun with him...an STI Trubor chambered for 9mm MAJOR! Man, this thing is awesome. Had a very sharp report and the same "punch" to the chest as a .38 Super, but it didn't have quite the recoil as a .38 Super. I was pretty impressed. I was able to keep the dot on target...with a friends .38 Super I've shot I couldn't find the dot right after the shot.

Anyone else get a chance to shoot this round yet?

[Steve Koski]

I shot a 38 Stupid race gun a few years back - the full meal deal. The dot didn't even leave the A zone at 10 yards. Friggin' amazing.

9mm isn't anything special, just 9x19 hot loaded. I have loaded 9mm major before and run a 9mm race gun with major loads, very nice.

[soundwave]

I always thought the 9 major case was a tad longer. Learn something new erry day here :)

[Steve Koski]

9x21 is a tad longer. 9mm Major is just regular plain old 9mm (9x19) cases loaded to higher than spec pressures. Well, there's a little more to it than that. Bullet selection, powder, work up, etc.

Do people reload the spent 9 major brass or is it to beat up after one fring at those higher pressures?

[Steve Koski]

I'm not sure. I've seen some 9 major primers that were flatter than flat., filled ALL the way out.

[MakeMineaP99]

Some people report you can get multiple firing out of 9mm major brass, the primer pockets normally loosen up first. I scrap my 9mm major after one firing, plenty of 9mm on the ground.

i played with it last winter. i didn't like it and other than a round or two less in the mag 40 is a lot easier to make major with.

[Steve Koski]

Even crappy old Unique will make major in a .40.

[Brass Nazi]

9mm Major? Isn't that like 10mm special?

[Steve Koski]

It's like Lieutentant GAP.

[Brass Nazi]

It's like Lieutentant GAP.


Except not as quite gay and proud?

[Mogollon]

If you throat the barrel properly, then you get several reloads out of 9mm Major. years ago i built one, in the pre-dot scope era, as 38 Super brass was expensive and thinner than 9mm. Was very pleased with it, and this was in the era of 175 PF for major. Then USPSA banned it, and I went back to revolver and 45ACP.

[Flexmoney]

An open gun running 9major shouldn't be any (much) different from an open gun running 38super at Major. Really, the 38s gives you more options on what powder to use to tweak the load for the gun (more powder capacity in the case).

It should be a combination of gun setup, springs, load developement...and the shooter.

If you're not shooting USPSA open, 9mm Major is rather an answer in search of a question !
I DO use my 9 major load in my production G34, but only at one club, as they like to throw a WHOLE stage of steel into their matches, usually 28-32 poppers of both sizes !
The G34 was my test bed for development of my 9 major loads & it has a STOCK barrel.
I quit loading the brass after 3 loads, because 9 is so plentiful, but it will go 5 loadings with the primer pocket still usable, 6 seems to be the max. I just had to test it !

I have a SVI IMM Open in 9x19 double stack in order.
I do not intend to shoot Major with it. What good is there to use more powder if it is only for plinking ?
I usualy stay below the max load in all the reloads I do.
Now , if you go hunting I maybe could understand the need for more power but just for plinking at the range ...?
What is the advantage ?
Is it to knock the heavier silhouettes down ?

[Steve Koski]

Most don't load 9mm to major unless they're shooting USPSA Open. Others might for the same reasons they might choose a 40 or 45 over a 9mm.

[VN350X10]

Charly,
The requirement for the 9mm major is based on the power factor, eg, Bullet Weight in Grains X Velocity in FPS. To make major, this needs to be a number equal or over 165,000. This is for USPSA competition, I'll need to refer to my rulebook to determine what the IPSC requirement is, I think it is 160,000.
The USPSA requirement in the past was 175,000, but this resulted in MANY blown up guns, & that was one of the reasons for dropping the power level.
The older level COULD be reached with a 9x19 ctg. but extreme care was needed to prevent disaster, as a result, the 9x19 was prohibited for a number of years.
With some of the more modern powders & the lowered level, it is easier & safer now to load, but care STILL needs to be taken to prevent problems.

thank you for the information Uncle.

I was not aware of this discipline, not sure we have that over here.

[Flexmoney]

You do have IPSC.

:thumbsup:


(there are various gun divisions, not just the Open guns and especially not just the hot 9mm's...though your SV would fit very well)

[VN350X10]

Also, in IPSC, major power factor for an open gun is only 160.(160,000)

Even easier yet to make with a 9x19.

For many years, 9x19 was banned in USPSA for an open, major caliber. There were a LOT of blown up Browning Hi-Powers for a while.The old (175) P.F. was brutal on a 9x19 !

Yes, we have IPSC here also.

[Steve Koski]

165 for USPSA major (any division), correct?

Only 160 for IPSC Open Major? Good golly miss molly. What happened to the good old days of just 175 across the board?

What's next, 155? 150?

[Flexmoney]

It's been stable for years. No grumbling for change that I've heard.

[VN350X10]

Steve, 160 is open major PF for IPSC, with a 9mm bore permitted, but all other IPSC uses 165 & a .40 cal min. for major.

(my MINOR loads make major !)

[Steve Koski]

I learn something new every day. When will it end?

[VN350X10]

Only when you don't ask a question Steve !

Besides, if you don't learn something every day, that day is a waste!
