I'm 3D modeling cartridges in Blender so as to get proper proportions when creating guns in the program.

Do the dimensions seem right, does anything jump out to you? I did research and think I got them right but it doesn't hurt to get a second opinion if necessary, just to be sure

Boolets.

Finding the actual dimensions for some of these was surprisingly difficult and at times I seriously questioned whether I had nailed the right ones and wasn't giving some of these cartridge types completely wrong proportions. If any /k/ommando sees anything off feel free to give me a shout, but I'm fairly certain they got the right sizes.
Also gadayum modeling the .50 BMG makes you realize how ridiculously huge they are, a fucking horsecock sized chunk of lead traveling at 1000m/s. Nutty.
It was also interesting to discover the 5.7 is like a mini 5.56, you know those bottleneck shaped bullets which are normally used for rifles. It's nice when a hobby makes you get further insight on the real world, it's educational
