I got a couple of boxes of what looks to be 9mm military ammo (FMJ likely 124gr with crimped in primers) the markings on the cases are "IVI 76" and some "IVI 81".]

I fired a few rounds and they seemed on the warm side, anyone know the velocity of those loads and/or any other info about the ammo?
 
I'm no expert for sure, but most military ball ammo is +P or even +P+.

Likely 1150 to 1300+ fps.

"IVI is Industries Valcartier Incorporées, a firm born in 1966 a Courcelette (Quebec). This firm made various calibers incl. 5,56x45, 7,62 NATO, 9x19, .50Bwg and others..."

Last time I chronied IVI Nato 124gr. FMJ out of my G17 it averaged 1270fps, its a bit warmer than most +P+ 124gr. factory loadings.

Sounds right on...I went snooping around the net after posting, and found a post that put it at 1276 fps.

IVI 9mm

This ammo is indeed +P+. It had a dual purpose..one for the DND HP pistols, and also for the SMG. The SMG had a heavy bolt that required a little more juice to push back. As it was a slam fire, the bolt had to be sent back past the sears and stuff to stay/lock open. Pistols were checked annually for cracked barrels, probably due to the age of the guns..b ut also because of the hot ammo. I wouldnt use it in an old collectable Luger or P 38...my 2 cents
 
I have the specs at home but I won't be there for another 6 weeks.

It's toasty and the CDN military are not allowed to fire this ammo out of the SIG's. They have Federal ammo for that. (Hollowpoint for Canada and FMJ for overseas duty.)

Are you sure about that, I could of sworn we use FMJ IVI in our P225's on the ship and for practice.

I always used IVI in SIGs too.

In any event IVI 9mm ammo is NATO standard, it isn't any hotter than any other NATO 9mm ammo.
 
cool :)

So the numbers 76 and 81 are the dates when the ammo was made right??

anyone knows what the pressure is of that load?

It was, and maybe still is, hotter than NATO standard. I was designed to be shot from the Sterling SMG.

AFAIK they didn't change the spec.

No it is NATO spec and has been since 1949, that is what the circle cross stamp on the base indicates. If the ammo was not NATO spec this would be absent and the ammo would be listed as an alternate Canadian type. The Federal etc natures that were discussed above are examples of issued, but not NATO standard ammunitions.
 
I'm pretty sure SAMMI rating for 9mm is 'only' 35,000 psi, 9mm +p limit is either 37,500 or 38,500psi, +p+ ammo would be hotter than that...


42,000 sounds pretty hot now I know why the guy gave me the ammo for free :eek: :)

Yes.

It was causing the frame rails to crack on the SIG's (alloy frame).

In the two years that I've been using the Sig p225 as Sea King aircrew, I've only ever fired IVI ammo.

I've never seen federal ammo on the pistol range or flight deck during proficiency shoots, especially hollow points.

Every round I've fired came from the 64 round IVI cardboard boxes.

Sorry about the confusion, the numbers I quoted are in psia (pounds per square inch absolute, you must add local atmospheric pressure), so the both our number our correct.

9mm standard SAAMI pressure 37400 psia max
9mm NATA pressure 42000 psia max
9mm +P+ no SAAMI pressure limit, usually between standard and NATO (boxes of Speer +P+ 115gr. GDHP have labels warning of pressures of 40000 CUP or 22% higher than SAAMI standard, which would be 45628 psia)
 
"...it was a slam fire..." No it wasn't. The Sterling was an open bolt firing, blow back operated SMG. Same as most other SMG's.
Yep. Standard, NATO spec, IVI Ball made in 1976 and 1981.
 
Have a look at the primers. If the primers are silver, then they are the newer IVI with a more sensitive primer. The SIGs had trouble with the older primers (gold/brass colour), with soft strikes. I experienced them myself.

All the newer IVI ammo is good in the SIGs. Both types are/were made to NATO spec.
