While this writeup is of some importance to someone in my field (security/protection services) it really isn't the cup of tea needed here. Since this is primarily a hunting based site, most on here require data regarding penetration and terminal performance. Primarily from the rifle rounds. Or even price points for the bullets alone for those of us that reload. Since FMJ's are illegal in every state (at least I think every state bans them) for the use in big game hunting then so far the products you are advertising are of little to no use to most on here. As for me, the only steel I use is at 600 to 1200 yards away banging the gong so frag rounds aren't needed. As far as kill house fire, every one I and my folks trained in were ballistic walled with movable targets and we used live ammo. We sure as hell didn't use steel targets!! Never in all my years have I seen one that did. So I am really not seeing the purpose of the frang training rounds. If someone is absolutely stupid enough to shoot steel close range they dang well deserve to get rebound smacked! Frag rounds are for populated shooting where a pass through would be considered dangerous. Not so you can make pretty colors in a target range shooting steel close range.
