Is anyone on here or know someone who is an engineer or technician, or know a good way to get in contact with one? I'm giving a presentation for a materials science of alloys class and I was lucky enough to get cartridge brass, and would like to pick another engineer's or technician's brain about the manufacture of casings alone: special drawing techniques, ways to maintain concentricity and lateral consistency round to round, metallurgy, anything really. Not asking anyone to give up any trade secrets, would just like to get some first-hand information, and thought this might be a cool idea. I was going to email Hornady to see if anyone over there might be receptive but only have time to post this for now. As a bonus, I'm going to be taking a scanning electron microscope of the edge of a ruptured case in the lab I work in, and I'll email anyone who helps out a copy, assuming the lab allows me to. Thanks in advance for your help.
