Had this for a while it is 30mm x 170mm what cannon would fire this one a Rarden! I do not think it is from a GAU. These are used to check the cycling of the weapon I gather for feeding & the ejection of the spent rounds the previous owner spay painted it a candy green colour which I have stripped off it looked horrid the nose fuse comes out but the rest the internal threads are stripped. notcool
Could some one please advise me as to the colour scheme the round would wear whilst in service so I can paint it up.

BM = ! who manufactured this one
I gather 96 is the DOM
087 Lot No.!
SPS = !

(On the Rt a 303 round for scale)

Appreciate assistance provided TIA
