steel target
 
Do you all suppose a suspended half inch thick steel plate could withstand a .338 Lapua? Building one for a friend and have no experience with a caliber quite that large.

Not sure, but I doubt it. I tried a 5/16 wall well pipe with my 257AI. 120gr Nosler solid bases, leaving the muzzle at about 2750-fps, punched right on through at 300-yds.

Your taking about a bullet weighing twice as much, with the same muzzle velocity, and as good or better ballistic coefficient. I'd expect it to punch through 1/2-inch plate.

It will work ONLY if its hardened steel. Regular steel will get dented all to crap and eventually break through. I have 3/4" regular steel targets i shoot with pistols. I cannot shoot 223 at them because the bullet will make very large divots in the steel causing unpredictable riccochets. You need to search google for ar500 steel targets. Thats the good hardened stuff that can be used.

You need 3/4 mild steel plates to shoot with a rifle. You need to hang the plates so they swing up when hit to send ricochets down. Yes, they will get dimpled but I have been shooting 3/4" mild steel plates for years without any breakage to the target it's self. I have broke chains, hangers and one frame. I usually shoot at least 100 yards with a rifle and 25 yards with pistols more powerful than a 45 acp.

Not sure this is real. Extremely improbable that the bullet could come back at a 180-degree trajectory. Not impossible, but physically extremely hard to get every thing to align just so.

you need AR500 armor plate.

If it is fake it would be hard to do. If you will notice the bullet hits the ground out in front of him. Fake video = awesome effects. Real video = lucky SOB. Hard to say either way I guess.

It's real, all right. I've had a low velocity .45 Colt 255 gr lead bullet hit a rock and bounce straight back, missing me by less that 12 inches.

You only need to experience this once to be a believer.

In the video you notice the target doesn't move. When a bullet strikes an immovable object the energy has to go somewhere. Either the bullet splatters when it hits the target or it ricochets in an unpredictable direction. That is why I say home made mild steel targets need to hang down and swing up. The bullet splatters or is deflected harmlessly into the dirt.

I don't shoot knock down targets on my property because the bullet is deflected upwards. When I am shooting my neighbor will ride horses and mules in the direction of the gunfire to calm the animal to the sound of gunfire. I have decent berms but they only do so much.
