7.62 NATO Bullet Factory. "Cartridge Case Feasibility Study"

grabcad

These are the drawn CAD files of the 7.62 NATO Cartridge Case Feasibility Study file in the attachment. They show the punches and dies to make "7.62 brass cases" from "3 draw cups". You will not that the drawings are not perfect, and some of the dimensions used as reference, could have been better defined as a radius. But other than that, they give you a good idea of what is meant in the book "Cartridge Manufacture" by "Douglas. T. Hamilton" . Other books like: "Dies Their Construction and Use", and "Punches Dies and Tools for Manufacturing in Presses" by "Joseph V. Woodworth", and "Cold Working of Cartridge Brass" by "L. E. Gibbs", are worth the read while they give you a good idea on how brass is formed, and what the annealing is for. Annealing is described in the feasibility study, with one difference; the annealing happens inline with the production process. So no need to anneal the brass, wash it and then dry it, and after that resume production. Now it happens all in line with the help of induction. I did not find the book that is referenced for in the text. You can buy it for money if you really want.They say that this production line can make up to 1200 cases per minute. If you want more good books, be sure to search for the names of the authors in google, and add archive.org to their names. www.archive.org is a good source for old (very good) files. You will need to know about machining, and heat treating. I cannot help you with that other than: "google is your best friend". I am not responsible if you get caught with a bullet factory/illegal gun manufacturing facility. I am just here to share the technology because this is what i have gathered in the last 2 years. And i want to keep the gun hobby/technology/fun with the living, so you can be my fellow gun enthusiast.This upload can be really handy if you want to make an obsolete cartridge for an old antique gun. I also uploaded the SAAMI specifications for brass and chamber sizes, on rifle, pistol, and shotgun cartridges. Internal sizes are not mentioned, so you will have to make that up yourself. Smaller brass volume gives higher PSI, to big a volume gives a weak casing, so be ware! Some pictures of head stamps on cartridges has been added, so you get an idea on what the possibilities are on the shapes. Remember: the stamp has got to be mirrored in order to get the text/picture the way you want it to be.Just for you to get an idea on how you can produce cartridges: https://youtu....
