Any information would be greatly appreciated.
 
The CBC 75 is dangerous, pull it for components.

CBC, 7.62MM X 51MM CALIBER CARTRIDGES RECALL: It has come to our attention that CBC 7.62mm x 51mm cartridges from lots dated 1975 may pose a serious safety risk. The specific cartridges in question bear the headstamp "CBC 7.62 75".
We hereby provide written notice to you that a potential hazard may exist with respect to outdated CBC 7.62mm x 51mm cartridges. There is a reported risk that such cartridges may cause excess pressure upon discharge and could result in serious bodily injury or damage.
Under no circumstances should these cartridges be used, given to anyone, or sold.
There have been isolated reports of rifles bursting as a result of excessive pressure in what appear to be these outdated CBC cartridges. An independent testing lab reports that it detected a peak pressure that they estimated to be in excess of 130,000 CUP in one out of a batch of 20 outdated CBC 7.62mm x 51mm cartridges dated 1975 that it tested.
CBC 7.62mm x 51mm cartridges are manufactured solely for military use in several nations around the world. CBC has not exported or sold any of these cartridges to or in the United States. These particular cartridges are not intended for civilian use under any circumstances.
In addition, a warning is issued for any CBC 7.62mm x 51mm cartridges from any year that bear a label on the packing material with the Spanish word "reengastada". That label was not affixed by CBC, and its application to ammunition is not yet clear.
Anyone who has, or believes they have, CBC 7.62mm x 51mm cartridges from lots dated 1975, or CBC 7.62mm x 51mm cartridges from any year with the word "reengastada" on the packing label should immediately contact the dealer from whom they bought the rounds, and call the following toll-free phone number:

A Good Deal, NOT, after what CanAm says above.

This is your lucky day, buy a lottery ticket then chase the guy who sold you this stuff and take a strip off him. If you could prove that he had knowledge of the danger, you might have a lawsuit ... but ...

... a lesson learned for all of us.

x2 on the CBC 75. International, sold it many moons ago. A good friend of mine had a Kaboom on a match built K98HB with it. It came in boxes, marked "Reformado" or reloaded.
The components, are very consistent. Throw away the powder and reload the cases with the pulled bullets. The bullets are excellent and accurate. They might be a bit difficult to pull, with an inertia puller. They are glued in place, with what I suspect is a sealant. Black and hard. The sealant, may have been the problem. I don't know, maybe Can Am can enlighten us?

CBC is Berdan primed. The cases are one-time only, but save the brass for the recycler. I shot a couple thousand Gold Cross remanufactured CBC rounds and got a mittful of money from the scrap metal dealer.

Your profile doesn't indicate where you are located. PM me if you want to resell that CBC ... I have the cure for its troubles.
 
Wow,

thanks for the information, im located in winnipeg, this was at the friedensfeld gun show. there was a person there also selling the dreaded israeli surplus ammo from november 1980, i steered clear of that but purchased the CBC ammo from another vendor. any idea on the make of the other stuff?
 
I think you could probably keep the powder too, Just empty all the cases and reload them with what you verify to be the correct amount.
 
Don't take the chance with the powder, some of the stuff I pulled, had a rusty powder in the case. That is a sure sign of deteriorating coatings on the powder.

Canam,

are you saying i should keep the bullet and case and toss the powder? is it the powder or case that is the problem?

Its the powder, burns to fast/inconstantly. If you have a collet puller, pull the bullets, dump the powder, and replace with a modern powder you know is good. If You don't have a reloading set up you would probably be better off selling it to someone who does.

Thanks for the advice, my reloading setup is in the mail. is the CBC stuff berdan primed?
 
The CBC ammo had two problems.

First, the necks were over-annealed and too soft. This is not dangerous, but the neck tension is inadequate for military purposes.

They (CBC) attempted to fix the problem by recalling all the ammo that had soft necks and re-crimping the necks. Did not work because brass was too soft for crimp to work.

This project mixed original lot numbers.

Then it turned out that one lot of ammo had rifle powder (ball) that had been contaminated with pistol powder (also ball). This ammo has caused quite a few KABOOMS.

CBC ammo with the re-crimping includes the bad lots so should not be shot. Pull the bullets, dump the powder and reload bullet and brass with good powder. Toss the fired brass.

If you have a quantity of CBC ammo that has not been re-worked AND that is loaded with stick powder it if very good ammo to shoot.
 
CBC is Brazilian. 'Companhia Brasileira de Cartuchos'.
Listen to CanAm. Especially when the manufacturer says don't use it.
Don't waste your time mucking about with berdan primed cases. Too much work and berdan primers are impossible to get.
"...probably keep the powder..." Um, no. You have no idea what it is. Pitch it. Keep the bullets, make drawer pulls out of some of the cases and pitch the rest.
'O' might be Sellier & Bellot. That'd be good. Not seeing 'OO' on the Cartridge Collectors list.
 
I'd pull bullet, dump powder, throw new powder in a known-to be-good weight, re-seat bullet and re-crimp.

I'd collect all of the old powder and sprinkle in the flower bed.
 
pull the bullets add a pile of varget and then send it to the taliban, don't forget to crimp the piss out of the bullets and seat them deep. Tell them its a gift
