Prolly a dumb question, but why isn't there a "slug" for the M203? I know it's a low pressure system, but with the new reloadable shells base (used for the cannon round etc.) that can take some pretty serious powder charges a 'slug' seems like it'd be possible. Prolly not made out of lead...to heavy, but perhaps copper or some alloy? For 25m and under work, it seems like it'd be possible. Maybe designed to seperate into multiple chunks on impact like the RIP round so it doesn't just punch a hole right through?

Gotta worry about the barrel as much as the case.... Hoop stress and all that.
Then there are the dinky mounts.

There's a reason M203 rounds and Mk19 rounds are different...

If you're going for direct fire anti-personnel, what's wrong with the weapon the M203 is strapped to?

Load up some 40mm flechette rounds, that'll do the trick.

ETA or find some M576 buckshot.

Don't they have 10ga adaptors? Isn't that big enough?

It could be a submunition type of thing if bbl toughness is a problem. The cannon round has a bore that is 1.125" in diameter. How about a clone of the copper RIP round that is that size?

The gun the 203 is attached to is 5.56...not nearly manly enough.

Yes. I have one. However, not commercially available, and I don't shoot it much.

I also have, 410, 16ga 20ga, 12ga, 4x410, and the older CANNON which is around a 3ga.

You have all the toys Grog. All I have is 20, 12, and the new cannon. I think the cannon could be used for this. Not sure what kinda fps it could do. If a slug was made from copper it could prolly move pretty good. Guess I'm going to have to buy a mini lathe...

My mini lathe was one of the best investments I ever made. Get one with a longer bed. GROG

Fletchette rounds

I know one person who had one blow up on him with NORMAl rounds and lots of stories from others of barrels blowing. They are already near pressure limit so there is no envelope to push left.

The cannon round seems to be able to handle some pretty significant pressures, and being a submunition it should minimize risk to the 203 bbl. It's a lot less likely to expand on ignition than a regular 203 round case. A stainless version of the cannon round would be pretty damn heavy, but I suppose that could be an option if the AL wouldn't get the job done. Allegedly it's the base that takes almost all the force of the blast, so an all stainless version of it could be made I suppose.
