As mentioned above it is IVI,, all recent and current manufactured.
I find it most interesting that IVI has learned how to make .303 ammo; hope they will be able to get it as good as the old Dominion stuff was.
Should anyone have access to box of this stuff, could they post a pic of a box (label showing) with a few rounds in plain view, and a close-up of the headstamp?
This would doubtless be a fine service to those of us who collect ammo.
Thanks in advance.

Wouldn't the weight of the bullet be 174 grains?
I thought that was the standard Commonwealth .303 British bullet weight.

They changed the bullet weight from 174 gr to 175 gr because the Mk. 8 and Mk. 8Z are loaded hotter than the 174 grain Mk. 7.
The Mk. 8 series was designed to be an all application round. From bolt action to machine gun.

Oh, OK thanks, I didn't know that.
Recce21 is correct
The 8Z ball ammunition is 175 grains (not 174).
This spring I dusted the chrony off and clocked the 175gr FMJBT at 2340 fps with a standard deviation of 120 fps. That is a shocking variation but this was also older ammo from 1992 before General Dynamic Canada bought Industries Valcartier Inc.
The 8Z ammo is driven by granular nitrocellulose powder where-as the Mk VII was driven by rod extruded cordite. Cordite burns VERY hot and is quite hard on burning out barrels.
Just so happens I will be writing an article on my blog featuring comparisons between the MkVII and Mk8Z ammunition. Here are some pics....

This following is a CF internal pub that I photocopied about 25 years ago, back when my career manager had sentenced me to 48 months in Dundurn Saskatchewan;
"Mark VIII Z
Official title- Cartridge, S.A. Ball, .303, Mark VIII Z.
This cartridge, the last of the .303 ball marks, was developed in the late 1930's and approved for service on 01 November 1938. The earliest headstamps noted so far have been K38 Mk VIIIZ and K1939 Mk VIIIZ. During World War 2 it was manufactured almost exclusively by United Kingdom plants, however one experimental batch by Defence Industried Ltd., Verdun, Quebec has been noted. In postwar years it has been produced by a number of other countries.
Intended for use only in heavy machine guns, its purpose was to provide greater long range accuracy and this was achieved by using a ballistically well-designed 175 grain boattail bullet of about 1.335" overall length. The standard British powder charge is about 36.5 grains of nitrocellulose Neonite propellant. Contrary to popular belief it is not a super-velocity cartridge and the official prohibition against its use in rifles and light automatic weapons stems only from the rapid barrel wear induced by the boattail projectile after the barrel has been used for Mark VII ammunition. The cartridge is loaded to approximately the same overall length as the normal Mark VII cartridge. The projectile comprises a gilding metal or gilding metal-coated steel jacket and a lead/antimony core without a ligthweight tip insert. The projectile is normally secured into the case neck by crimping or coning into a flat fronted cannelure. The standard of accuracy for the Mark VIIIZ demands a figure of merit of 8 inches at 600 yards. Like the Mark VII already discussed, the Mark VIIIZ may also be found with the Arabic 8z headstamp after 1945. Specifications for the MkVIIIz cartridge call for a mean velocity of 2,400 +/- 40 fps at a pressure of 19 tons, with no single round exceeding 20 tons. The pull required to withdraw the projectile from the case neck is 60 lbs."
From the current CFTO, C-74-305-DCO-TA-000
The bullet is 1.30 inches long and weighs 175 grains. The bullet is boat tailed and consists of 98/2 lead antimony core covered with a gilding metal jacket.
The propellant used in the Mk 8 cartridge is a double base commercial powder CF 7500; in the Mk 8z the single base C1 (CMR 100) is used.
The average velocity shall be 730m/s +/- 15 m/s and the standard deviation shall not exceed 12 m/s at a distance of 27 meters from the muzzle

I don't hear that often so excuse me while I make my wife read this and revel in it
