20mm sub-calibre help please.

[Dylan du Preez]

Hi everyone, I'm looking for any information on this 20mm sub-calibre round. The previous owner told me it is a 20mm spotting round but I haven't been able to find any more information on the round. The head stamp reads 20mm 64 MPA and the dimensions are as follows: length of cartridge 68mm, case length 27mm, projectile width 20mm, rim width 22mm.

A sub-cal round for a LAW rocket? Just a guess.

There were various spotter/trainer rounds of about this size - a couple are shown in the photo from my Ammo Photo Gallery below. They were all for anti-tank rocket launchers or recoilless guns of one type or another, with the ballistics adjusted to match.

The 20x22R is what I was thinking of, but I wasn't sure of the dimensions.

Thank you for the help guys, do you perhaps have drawings or sectioned examples showing the internals of a similar cartridge?

The LAW used the 9mm (necked up 7.62mm Nato) spotting round

Yeah I realized that after. I was thinking of something else I guess!
