Title: Caution with unknown ammo
Post by: oldfart on November 12, 2015, 09:30:59 AM
This is common sense, but I'll say it anyway.
Found this in the grass at khsc action bay.
It is obviously a reload. It's also obviously way over length.
It was probably ejected from a pistol while clearing a jam...not surprising.
There is good possibility that this is a "major 9". Custom loaded for a race gun.
Higher than normal pressure to achieve uspsa or ipsc major power factor and allow the compensator to work more efficiently.
If such is the case, then the gun would be built with a match or custom fully supported chamber to contain the pressure.
Shooting ammo like this from a conventional pistol might cause the head to rupture sending a jet stream of gas into the mag well.
The magazine will probably have live rounds in it....not good.
The usual result is the mag gets blown out of the gun, possibly destroying it and scattering ammo into the dirt.

Btw...putting on my csi hat.... even without dissecting it you can tell quite a bit about it.
1. The distinctive gold color bullet looks like montana gold
2. It has a flat, not hollow tip. Probably the 121gr. Mg bullet as seen on their website.
3. Total wt is 191 gr subtract approximately 60 gr for a casing=131 gr minus 121 gr=10 gr.
It wouldn't surprise me if a hot comp setup for the 121 mg bullet runs around 10 gr of some powder.

Might also be a normal 9mm hand loaded for a Glock.  seems like Glock BBLs have a real long throat, re loaders can seat bullets longer for these barrels, definitely wont work in a cz75 without getting jammed into the lands.  lol  :o

Ya. I do that but the limit seems to be the magazine. So can't get out as far as I would like.
That round doesn't fit comfortably in a glock mag. It does fit a 1911 size mag rather nicely.
That mystery round could be loaded for a 1911 hicap with 9x21 bbl????
Or it could just be a loading error on the dillon.
I say it was loaded on a dillon with dillon dies because of the pronounced hour glass shape typical of dillon dies.

Thank you OF for reminding us not to shoot ammunition we know nothing about. It is vitally important that we are always cognizant of this. Most people don't realize that a decent portion of the cartridge is unsupported. Or not well supported. in a lot of very popular semi-auto pistols. This is why if you Google GUN KABOOM you will find that Glock's are at the top of the search. It doesn't mean they are prone to it so much but it does happen due to a portion of the cartridge being unsupported. This and Google GLOCK BULGE and you will find other issues surrounding unsupported cartridges. I am not picking on Glock's per se. I just happen to own one and have had some experience with the Glock bulge issue.

I started a couple of threads quite a while ago. I resurrected them here in case any one is interested.

Never shoot someone else's reloads:

Before I read your description I thought to myself that this reload is using a MG bullet. It does look exactly like the ones I have seen. It is too bad that the powder cannot be identified. It would be interesting to see what the load really was.

Thanks again for this info and reminding us to be careful with unknown ammunition.  :worship:

Thanks for the glock bulge thread....and I'm talking about ammo...not appendix carry. :rofl:
...
About the powder, I'm guessing it might be vv3n38 as that's the hot racegun setup.
When I put on my extra large csi hat maybe I'll dissect it and do a microscopic comparison to see if it matches the 3n38 that I got.
...
But ya know....I'll bet there aren't but a couple guys running 9x21 hicap rigs on this rock.
So that narrows down the list of suspects.

Appendix carry? Is that what we are calling a beer belly these days?  :rofl:

Let us know what you find when you take it apart. You got me really curious about this round.  :geekdanc:

Tho I know it's too long. I tried it in a 9mm gauge and a G17 bbl.

i found one of those on the ground at the HPS match on the first sunday of december
it had a red sharpie line all the way around it
didn't load it in any gun, of course
