Rimless 20mm case , 97 mm long, Valcartier 68 manufacture, C67 stamp. straight case. Any info would be great. Cheers G

For both of your inquiries, it looks like the cases are the Cartridge, 20mm, Blank load for Neutrex Mk II. This is an EOD disruptor used to destroy bombs and IED's.

The cartridge came in four different charge weights 70, 75, 80 and 85 grains. It also has an electrical primer.

The case is in the third extrusion stage of manufacture for the .50cal cartridge case, so before it was necked.

There is also the possibility that it is a Cartridge, EOD Special (Avon). This cartridge was developed as a low cost replacement for the disruptor EOD known as the Horseshoe.

I can't find which identifier was used on the base of either kind of cartridge - both of mine are stamped C67 - and can't find anything on the C68 mark either.

They were likely made by Proparms Ltd. in Quebec.

Thanks for the reply.I'll delete this one and go with the first post. Its boxer primed and definitely straight cased, same length as a 50 cal Made by Valcartier Ltd,

As a note there is a red line around the inside of the case approx 3/4 of an inch down from the rim and another line about 1 3/4 inches down .37patt identifies it as a EOD disrupter pretty sure thats what it is. Thanks for the replies. G
