What is this from? Subcal round??

[MissingSomething]

I believe this is some kind of British subcal cartridge. Anyone confirm this? Anyone have a photo of a complete round with projectile?

Headstamp is RG 90

Rimmed case
Rim = .346"
Rim = .066" thick
Case = .295" wide
Case= 1.114" long

This one is obviously damaged.

Any help is appreciated.

first impressions it looks to me like its the cartridge for initiating charge bags on tank ammunition,think these are called tubes or vents,just my thoughts may be wrong can someone else confirm what it is

See my answer on the IAA forum.

This is the remains of the .22 Hornet blank in a 9mm SMAW spotter round from the SMAW anti-tank rocket.

For those unfamiliar with the weapon, the rocket launcher has a throwaway spotting rifle attached loaded with five rounds of 9mm spotter that gives a flash on bullet impact.

The round is a necked up 7.62 x 51 cartridge with the head (The base) bored out and a .22 Hornet blank inserted. When fired it works on the high-low pressure system,the Hornet case discharges gas into the larger case which in turn propels the bullet.

The Hornet blanks were originally bought in US commercial cases but are now made by Radway Green and bear a headstamp of RG and date.

The original design was not necked up to 9mm and used a long lead 7.62mm bullet but it was found unsuitable and the production version was made in 9mm.

There is a sectioned round on the IAA Cartridge of the Month page for October (?) 2005.

Hey now.. don't get down.... closer than I got....

I have been collecting for almost 20 years and there is no end to the learning that I have to do.....

Only twenty years? A mere child!

I applied for my first Firearms Cetificate on my seventeenth birthday forty six year ago.... and I already had a lot of different "bullets" by then!
