Wow, the kid got off like that! Just plain rediculous! Glad to see the doctors was wrong about not being able to walk again John....I'll try taking a picture of the plate, the bulge is not really visible on the other side of the plate, the only way I could really tell is because I painted the plate and the paint flaked off on the other side. The plate is hanging, but didn't swing much when hit, probably due to its weight. Oh well, time to order up some AR500 steel plate

Well I tell yah Joel 316 "Flaked Off" paint is considerably different then a Bulged back of 3/4 plate steelLOL. Any how now I'm sure you can read a tape measure cause it sounds like your target is mild steel after all.Shoot at that thing in peace,it you will never shoot it two much( Practicley speaking) Did you say 12"x12" That's a big plate,I think just don't shoot at it under 25yds(There will be "High Power Bullet Splatter") Full Metal Jackets would be the most dangerous to bystandards or your self.

The most common type of steel is called A36 which is a ASTM designation. The 36 means that it is capable of 36,000# in tensile strength. They have grade A572 and other grades which are 50ksi but is not that common. The AR plate which stands for Abrasion Resistant is not very common in 3/4 plate and can have tensiles in the 80ksi to 100+ksi. AR plate is brittle but not glass like, more that it is not formible i.e. like bending it to 90' will cause it to break in two. In all probability your plate is mild steel (A36) and will hold up to the 223 easily. For a safety precaution I would attach it to a stand so that it hangs tilted towards the shooter so that when the bullet strikes the steel it tends to put the bullet down into the dirt if you know what I mean. My 2 cents. dale
