| How much of a backdrop is needed for this stuff? |
|
You still need a pretty darned good and HARD backdrop.
For example.... I shot some 1/4" mild steel pistol plate with XM556NT frangible and it nearly penetrated the steel. I'm talking a huge crater that slightly pushed through the metal, but didn't quite penetrate. Harder steel isn't a problem... but any soft materials and the frangibles pretty much act like regular bullets. I've shot them through 2X4s and the zing right through. |

FWIW, I sent Old_Painless a box of these frangibles for one of the old original Box O' Truth posts here several years ago. He didn't test it against steel, but it penetrated more drywall than I would have thought at the time... http://www.theboxotruth.com/docs/bot4.htm |

I've been reloading with frangible .223 and 9mm for about six months and use them on some AR500 targets.
I contacted the bullet manufacturer for ideas on how to make a range out of a storage container and he recommended sheets of the AR500 steel set vertically so that bullet impacts were 90 degrees to assure the bullets break up completely. I have seen some places that sell the sheets in various thickness and I'm wondering how some sheets1/4" or even 1/8" would hold up. |
