Most have been posted one time or another.  Just finished and its really about the section of the XM645 at the right.  These were part of the SPIW (special purpose individual weapon) of Project SALVO in 1957-66.  It started with 42 companies bidding against one another and ended up with only 10 submitted proposals.
The second from the left is a XM144 Tracer that burnt the crap out of me.  Also, a XM645 with 6.35 copper plated bullet in a clear sabot (say-beau) and a moveable primer to unlock the gun.  Its he most complicated of the SPIWs'.  These were all designed for against body armor at 150 meters.

Damn cool. Thanks for posting.
In the Marines I got PT Thrashed on Christmas by our Drill Instructor because he blamed the death of Christ on recruits.

Sorry to hear you got a burn doing these. Obviously this is a dangerous hobby cutting apart old and mostly unheard of cartridges. Hope you heal up soon.

Did those type of rounds work at all?

Cool though. I've only seen flachet shot shells before.

The effectiveness of flechettes isn't hard to figure out.

Mostly a collector item, with none issued across the board. They didn't work.

Get them to move at 10,000 fps and I'm in. But only if concealable. And there is the challenge.

I'd be curious as to how or what effect the fins had on the bullet trajectory?

EX: an arrow will somewhat compensate for a cross wind by turning into the wind during flight.

There is a great book about the SPIW program out there if you can find it.

As usual, WGG's sections are first rate.

Only good dart round was for a 105
All 8000 of them

Heard that our military stopped using them for humanitarian reasons. Don't dare hurt people that are trying to kill us...

Also 105mm and 155mm for arty.

An old neighbor was Marine arty in Vietnam. Told me about stopping an NVA assault on his firebase with 155mm beehive rounds in direct-fire. Basicly vaporized the ones closest to where the shells burst open.

So as far as the 556 rounds...did they just not function/fire from the gun? Or did they just not cause enough wounding? Or accuracy was shit? Or maybe all 3?

I could see that making hamburger out of a large group that is at just the right sweet spot.
