Oh, hey Rusty, I didn’t know you were working on this! I already made graphics like a year ago for this prop. I’ve been meaning to do a built-up and thread on it but my plotter got damaged in the move and I haven’t had a chance to get it fixed yet.
In case it helps, here you go. My vectors are all based on actual measurements from the ammo case that I have (found on eBay).

Based on color swatches I have, I decided on the following Oracal colors for the vinyl: 031 (red), 090 silver gray metallic. Note that you have to use the 651 Intermediate Cal series and not the premium series, because the premium metallic have metal flake in them whereas the silver in the intermediate series has the same flat (non-sparkly) look as the silver on screen.
