Had some time to go back out again today to try something a little hotter :) Fired again from 15yds, M193 from my 16" barreled Stag Model 1L. Easily Penetrated the steel plate. I need to take some weight figures on the plate, as some have commented plate might be harder than cold rolled steel. 60*F outside
