In the past alot of people talked about the type of steel they used for their gongs and targets.

What type of steel will xm193 NOT penetrate at 100+ yards? There was a certain spec for the different steels that some would cut through like butter and others were ideal?


Basically we are having a few either, 12" x 12" targets or 12" diam targets made. Any recommendations?

Most rifle proof targets are made from 500 brinell steel.  I am not sure what that means.  I did price some locally and a 4x8 sheet was something like $1200 IIRC.

And the big thing for when you get that sheet is to make sure that when it is cut that it stays at 500b and doent soften.
I've used 1/2" thick mild construction steel for shooting at but the minimum I've shot it at so far is 300yds. At that distance with a .223, I get a very small dent and the steel will handle thousands of rounds. I'm not sure how it would react at 100yds though.

goto wwwmgmtargets.com  they have alot of steel targets and have free shipping.  the 500 brinell steel is the hardness of the steel.  the lower the number, the softer the steel.  harder is allways better

Ive got one for you.. DO NOT use the large 12"x8" steel plates the railroad uses to set rails. They are tempting... Ive got an entry and exit scar on my calf from this experiment.

I use AR400/500 steel 3/8 inch thick, and it stops all pistol rounds flat.

A cheep alternative is to weld together two pieces of 1/4 inch mild plate.  M193 will penatrate the first plate but the second will absorb the round and only dent.  I get a whole season of shooting out of these.

And there you have it...dont shoot at it under 300yds. I would probably say dont keep it as a static target also, I set mine up to swing and I get a small dent with .223 and a moderate sized dent with .308.

Also mount the target on an angle (tipped forward toward you.  That way the fragments and shrapnell will deflect down into the ground at the base of the target
