If you Google “Maximum Cartridge / Minimum Chamber”, you can find SAAMI-approved specs for various rifle cartridges. For anyone working on a new cartridge design, it would be helpful to have blank drawings for cartridge and chamber, to which you can add your own proposed (non-SAAMI-approved) specs.
Below are GIF, PNG, and PDF files with blank drawings I’ve prepared by examining existing Maximum Cartridge / Minimum Chamber drawings available online. Use as you see fit, at your own risk.
PDF (Adobe Acrobat) file format:
To add your specifications to the blank files in GIF or PNG formats, use a graphics program.
To add specs to the PDF file, use the latest version of Adobe Acrobat Free Reader. Click “Sign”, then click “Add Text”. Set the font face and size. I would use a font size of at least 18. Then add your specs and save the file under a different name (i.e. not “SAAMI blank”).
