Hello all and thanks for having me! I would have done this in an introductory forum, but I didn’t see one listed. A little background info about myself: I’ve been a collector of militaria since I was a little kid, but I regrettably sold a lot of pieces along the way that I should have hung on to. Anyway, my main focus is collecting belt-fed ammunition and their belts/links used by the U.S. Besides the already mentioned hobbies, I’m also an avid shooter/outdoorsman. I’m a manufacturing engineer by trade (and have spent many years as a machinist), and I also collect blueprints. I enjoy solid modeling, and like to model firearms and their components.
I’m currently looking for drawings & blueprints related to 30mm ammunition and their arms; specifically, I’m looking for drawings for the 30x113B used in the Apache’s M230 chain gun. I have aspirations of designing and building a semi-automatic, belt-fed, 30mm cannon (to be registered as a destructive device in my state). I’ve already requested the STANAG’s for 30mm chambers and their links, but NATO cancelled them. I’ve sent a letter to NATO requesting copies of the cancelled documents, but haven’t heard back from them yet. Anyone have any drawings for the 30x113 to include cartridge case or projectile?
Also, I recently picked up (from another board member who turned me on to this forum) a bag of links marked “30 WECOM.” These were in a ziploc bag marked by sharpie. I’m familiar with WECOM developing a cartridge for use in helicopter guns, but I’ve never seen pictures of the links used to verify what I have. The links have no identifying markings (lot numbers, cage codes, etc.), but they seem to fit the diameter of a 30x113 (I don’t have any WECOM rounds lying around to try them on). The link fits well, but there appears to be a little space between the link and the cartridge where the “prongs” are supposed to snap into the extractor groove. Can anyone positively identify them as WECOM links or something else? Any help would be appreciated.
