Hopefully this hasn't been shared before.

Check out this crazy double bullet .308 - The "7.62x51mm M198 Duplex"

This is a screenshot/x-ray from the video.

They shoot out behind the other so the first penetrates and loses all it's energy creating a clear path for the second bullet.

Crazy.

Cool.

Would this work through a regular hunting rifle barrel or is it for a special firearm only?

Did a quick good for 'Project SALVO' like it labels the cartridge in the video. Seems this is part of a whole bunch of experimental weapons stuff, not just 1 round.

Interesting.

Kind of like "Metal Storm" ammo for regular firearms I guess?

For shooting a deer, AND the other deer behind it?

Metal Storm went belly up a few years ago didn't they?

No more crazy toys from them

This is a DUPLEX round, they were developed for other calibres many years ago [last century] for machine guns to get as much lead in the air as possible in a given time, not very accurate, just mass fire power.

Last century made some for 45/70 using RB to see how they performed.

BB.

So it would work in a standard barrel then?

Looking at it I figured you might get some funny pressure issues?

[bunnybuster]

I would not attempt to make duplex loads for a necked case,but I have done for a 45/70,no risk of the second proj canting and jambing in the neck

Be safe BB

These must do wonders for your barrel life

As long as nothing slows down that first bullet I suppose it's ok.

You wouldn't want to have left a blob of grease or anything in the barrel though

Kaboom!

Full-auto barrels last so I guess it's ok?

Up to a point.

Full auto barrels will be designed with their high rate of fire in mind though.

That's academic though, how fast can you really fire a bolt action after all. Not 600 rounds per minute I think
