I posted something similar for ideas on testing .410 self defense shells. So, the premise is that I get some of the most popular 12 Gauge self defense rounds, fire them at some sort of medium, record the penetration, devastation, and expansion (on slugs), and post them for y'all's entertainment. I need some ideas from you as to what the medium I'm shooting should be and what rounds you want to see tested. I'm not made of money so I'm probably not going to be able to shoot up some 60lb chunks of meat, although that would be the best way to go. So give me some ideas besides the obvious ballistics gel, and tell me if you even care to read the results. Also if anyone lives in the Columbus area and wants to chip in and join me and the wife for a day of shooting please let me know.
