target steel ?

[ghostinthewoods]

I picked up a piece of steel today label on it reads, hr carbon steel plate q&t400 brnll. Its 3/8. Lady said a guy ordered it for shooting and never picked it up so she gave it to me cheap. I'll be shooting it with a 7mm ultra at probably 800+. Will it be OK?????oh I think I can see a place on the label where it says ar400 too but its kind of rubbed off. Any help would be great.

400 is good to go, handles my 300wm at 300yd

Past 300 or 400 should be ok

I made some targets at work out of 3/8" AR-400
They handled .308 at 300 yards. Not even a dimple in the steel.

How does it hold up after several thousand rounds? We've found that even the thickest stuff gets all puckered after heavy use, but that may be the quality.

I just made them a few weeks ago. They only have 20 or so hits so far.
Time will tell I guess!

Thanks for the info guys, I guess I'll give her hell.

choot em Liz!!! den you know

At long range you should be fine. Faster bullets might put some damage on it, all you can do is shoot it and see....

at worst throw'er back in the oven

Thats a bad idea

 

[Waco]

this is my 10 1/2" ar400 plate, and my 18"x24" A-36 humanoid target
the A36 target will be shot at 900 yards only to extend the life of it.
made them both at work
the AR400 plates cost $10 each, and the other was $39

Presume the Q&T is quenched and tempered, and the 400 brnll is a reference to a Brinell hardness (i.e., 400 BHN), which equates to about a 200ksi tensile strength.
Sounds like some ASTM A514 AR400 plate.

Would mounting so it can swing and at a slight angle help?

Absolutely, if there's a little give in the target, or the impact is partially deflected, it will help the targets last longer as some of the engergy is deflected.( although it should hold up to several thousand rounds, unless you shoot it with a .224 bullet at high velocity at close range.
If you can get some used conveyor belt or fire hose to hang the targets with, it will work out better than if you happen to hit the chain hanging the targets. Speaking from experience here.

Here's my steel target I picked up at the junk yard for under $20. It's standard IPSC size at 5/8" thick, weighs 80lbs. Have it hanging by chains from a saw horse. The impacts were from 2050 yards plus with the 338 lapua. It also holds up with no dents when shot at 1200 yards. haven't shot it any closer than that though, I know it's hardened steel but to what point I'm not sure.
