We were trying to field totally automated artillery during the Bush years.

Can't know for sure but I do know the french Caesar 155 L52 use something looking exactly the same from a sort of speedloader filled with several of these blank rimmed rounds, making it semi-automatic.

So this must be a NATO standard.

However it absolutely does not look like a 7.62x51mm. It has a rimmed and straight case, not necked.

Can someone give us insight on the caliber ? Is it 20 gage ? .410 ?

I assumed these big bore canons would use a standard 5.56mm or 7.62mm to ignite the charges, but it appears not to.

It's probably just a unique blank cartridge, but I find it interesting and I'd like to know more about it. I started to do AROTC in college and my teacher the first semester was an artillery captain, and I got up close with an M777 at Marine Week a few years ago, but I never bothered asking about the specifics of firing mechanisms. I looked up "howitzer firing mechanism" on google and came up with a bunch of drawings of old British howitzers which look like they used .303 blanks

Says the inbred chinless luddite neckbeard

They're essentially just big primers, and are labeled as such. They don't share case dimensions with any small arm that I'm aware of either.

I found a company called Island Ordnance Systems that makes an "M82 primer" for 155mm howitzers, so that's probably what it is.

Similar shape and has a primer etc but its not a rifle blank
Main difference is due to the significantly higher chamber pressure each primer needs a block or plug between the firing pin and the internal primer cap and the main priming powder charge.
It lets the initial firing pin strike forward onto the primer to flash forward into the priming and the bulk propellant but then slides backwards to plug the channel.
Otherwise the primer cap would get driven out past the firing pin by the chamber pressure to jam the mechanism
>>33313039
The "plunger" pushes back into the "body" like a seperate captive firing pin

wow this is old, where is engine hand crank location?

>>33313338
Yeah, we should totally have kept a bunch of overly complex, underpowered, half a century old vehicles in service. It'd have been great.

Maybe see if we can get a fresh batch of Strv81 to put back into service while we're at it?
