Does any one know the specs on the IVI 9mm that is issued. Bullet weight velocity and how it compares to standard commercial type ammo and other NATO ammo.
 
I do not have the current specs, but can tell you that IVI 9mm in the 64-rd boxes that was issued to the CAF during the 1980s and into the GWOT years was considerably hotter than its civilian equivalent. 124gr FMJ Bullets are NATO standard weight. It is the powder charge that differs (or differed) from civilian-equivalent ammo, lending the CAF-issue ammo its increased velocity which was originally designed to function reliably in blow-back-operated submachineguns such as the WW2 STEN and the later C1 (simplified Sterling) SMG. I do not know of the current specs have been down-loaded to commercial-equivalency for the new SIG M17 sidearm.

A bit of 1980s trivia for you - my original HK MP5 owners manual stated that Israeli IVI "Black-Tip" and Canadian IVI 9mm ammo were to be avoided lest it damage the firearm. If those specific types of 9mm were to be used, the MP5 was supposed to be fitted with a stiffer Operating Spring.

Nato Ball (Parabellum) CDN MK1​


The 9 x 19 mm NATO Ball (Parabellum) CDN MK1 cartridge can be fired from either pistols or machine guns. The nominal projectile weight is 115 grains and the cartridge uses a brass case and a boxer primer. A special double-base smokeless propellant is used to minimize muzzle flash and the amount of unburnt powder. Cartridge lot 304IVI79, manufactured by General Dynamics Ordnance and Tactical Systems – Canada, remains in use as the NATO reference. Non-toxic primers free of heavy metals are available.
  • Nominal Muzzle Velocity: 380 m/s.
  • Accuracy: Extreme Spread at 25 m < 7.6 cm.

Wasn't the ball ammo too hot for the Sig pistol as well?

I only ever seen Winchester Ranger when the Sigs were out.
 
So according to SP641's specs, IVI is only 20 m/s faster that standard American Eagle ammo. Seems hardly the barn burner that some people have been saying
 
I believe it was changed after the SIGs came in. I remember one of our gunplumbers saying it was hard on them, this was in the mid/late 90's.
The stuff from the 70's and 80's was pretty spicy through an HP.

IVI 9mm has been significantly reduced in power since the 1990s when it would cause the Bolt of my personally owned C1 SMG to hit the Receiver's End-Cap! It was outright damaging to the Browning Hi Power Pistols, resulting in Slide/Frame battering and eventually loose tolerances and consequent degradation of accuracy. It was even worse for the SIG P225 and P226 pistols, with their softer aluminum Frames.

Check the dates on any random boxes of military IVI 9mm packaged 64 rounds per box that you happen across at local gun shows. If it is dated pre-2000, proceed with caution and fire only from a robust PCC or a handgun with a stiff Recoil Spring installed.

Only 20 m/s, now refigure your math with a 124gr bullet at that speed and higher pressures instead of a 115gr bullet. That older IVI was intended for sub-machine guns and being intended to run the slides reliably. I own a 1984 Sig P226 that was one of the RCMP trials pistols that developed cracking along the rear of the frame rails. Sig remanufactured new frames with the old serial numbers, had the RCMP stampings nicely ground off the left side of the slide so they look like they only wore some blueing off from holster wear, nice job. The new frames with new parts were matched to their slides and with 2 new 10 shot MecGar mags, the pistols were put back in their boxes then surplused (never happens anymore). I bought mine in Edmonton from Milarm. Since then I've met guys that bought one of these from various parts of Canada. They are still amazing pistols to this day.
 
I have some IVI 85 and 95 I could run over a chronograph. Question is, what firearm to use? Handgun or period correct PCC?

I also have an issued level 2A panel I could try it on.

I always thought the IVI ammo was 124gr?
