At my last mid-power launch someone gave me this unidentified reload. All I know is the obvious, it's a 2 grain 29mm CTI, presumably a G. My first thoughts were a G80 because the propellant has a brownish look to it but when I look at it closer it looks like grey and brown, so possibly some oxidation. Maybe the coloured dots on the ejection charge cap tell part of the story. I am sure one of you CTI gurus will know what it is.
