I make a 165 grain .40 cal HP made by Erik as well. I have a very particular blend of alloys I use that gives PERFECT expansion at around 950 fps with almost 330 foot pounds and a power factor of 157. In the last few weeks I've been mimicking the FBI's ballistic gel test through particular barriers they specify in a kit I built. I've made it relatively cost efficient for myself to have definitive results just as the commercial bullet companies do. I want to start marketing this kit but I'm not sure if the investment to make a few and sell them is even something people would be interested in. I have a few ideas: Make the kit to be sold and used by the purchaser, use my own kit and meet people at the range to test bullets themselves with my equipment, or allow people to ship me their bullets to be tested and I will video record it and send back the results and specs. I am an avid caster and reloader and I'm going back to school to become an RN so I'm hoping to make a few bucks to cover some of the $42,000 bill. Do you think anyone would even care to have their bullets tested at the degree a manufacturer would? To ensure their bullets live up to the expected standard in which they use them for?
