Duck Billed Shotgun

Question regarding shotgun pattering at close range. Is there such a thing as duck billing a shotgun barrel. I have read in years past that the barrel was flattened/duck billed to open the spread at close range with some kind of shot(not slugs).Was this an idea that just never worked or is there some truth to this. Just curious. Thanks

This was done during the Vietnam War with the Ithaca 37 Shotgun. It was actually a duckbill attachment made for it.

Used in the Rhodesian bush war as well. Read Red Zambesi by Joe Hale. I knew the author personally, and he told me about the incident where he shot a terrorist with a duckbill shotgun.

My understanding was the device spread the shot horizontally as opposed to a regular open choke that gives you a circle pattern.

Good luck

There was a duckbill used in VN on Ithacas as stated.
There was also a "duckbill" external choke device sold to LE/MIL back in the 80's that could be mounted on several models.
Both threw a horizontal shot string.
The later model mentioned advertised a 8 foot wide shot string at 25 yards. (I do not recall what shot size this was with)

HK/Benelli also offered a duckbill on the M1 Super 90

One version was the "A&W Diverter". It screwed onto the barrel, and gave 2 to1 or 4 to 1 dispersion, depending on what the customer wanted. It worked well with bird shot, but it never was successful with anything bigger than #4. It made #00 very erratic, so was never popular with police.
