I encountered a piece of projectile's envelope.
It is made most probabley from Aluminium and I measured one land groove 4.4 mm (0.17") wide.
Did anyone ever encountered such a projectile?
Any information will be apriciated.

A picture of the projectile fragment might help in providing information.  Tipically in the U.S. the first thing that comes to mine when we have a projectile with an aluminium jacket is a bullet made by (winchester silvertip) I was thinking of an aluminium case when I said CCI, my mistake.  However, in Israel I'm not sure, Axel Manthei might be able to offer more help.

Winchester silvertips used to have aluminum jackets.

First, thank you for your replies.
I Know about the SilverTip family. The fragment I have is from a much larger caliber (over 20 mm to my opinion). I thought more in the direction of a flare or grenade, but I dont recognize a rifled weapon which fires them.
PS,
I received information about the M203 grenade launcher. It have 6 lands with right twist, but I dont have information about the lands width. If anyone have this information, it will be of great help.
I will try to upload some pictures.
Have a nice weekend,

Lior,

could it be a 20mmx139?
The HVAP projectiles have an aluminium body in which the hard core embedded.
The one we have in the database is painted black...

Maybe bigger calibers have the same setup?
Any picture of your item available?

Greetings

As I suspected, it is a piece of 40 mm projectile, fired from M203 launcher.
I thought of writting a paper about big caliber projectiles (20 mm and up) as I have some interesting stories in that field.
I'll be happy to cooperate with other experts, who have similar expirience, and publish a paper on the subject.
If anyone is interested, you may write to me and will issue the paper togather.

Lior,

Did you ever get the measurements for the L & G on the M203? I'm curious if they differ from an M79 both in the number, direction and width.

Thanks

Bill

6 L & G, right twist, 4.3-4.5 mm width.
