| I have several old brake disks laying around. If I were to shoot at them 100yrds with 7.62 or 5.56 would that be safe (all shooting done on farm in middle of no where). Beyond the obvious problem that they have a hole in the middle. I would like to make some good metal targets to shoot at but those cost $ and these are free. |

Eh, dont shoot any steel core at them. Also, keep in mind.. You have no idea where they may end up. Honesty why not? Im being serious, not trying to start a fight. We shot Steel targets @ 100y all day long using M855 in the Corps Hmm, good point. Hell with it, go for it.

It was gramp's Samurai and my little bro drove it till the muffler fell off then parked it. I decided to get it going agian and drove it home. I couldn't really hear the brakes grinding because of the exhaust noise... then I took the wheel off. I drove it like that about 8 miles across Denver. |

I want to buy one or two of those 1/2" thick 500 brinell plates from Widener's. $59.50 each.

| Disk brakes are normally cast iron. Cast iron is brittle and a HP rifle will just blow chunks out of them. If you want a good target, try and get some railroad rail. Lay it on its side and shoot the top of the rail. There is little chance of even Ap rounds going through. I have put 30 Cal AP rounds from a 300 mag right through the 3/4 inch webbing of railroad rail however (like knife through butter). |

Ricochets suck if you're at the end of one. There are many better things to shoot at. Shoot at those rotors and you're a Darwin candidate. CJ From 100 yards away?  http://www.youtube.com/watch?v=mn0MFqP1js0
Was that NT in that video?

That looks to be less than 50 yards and it is a .50BMG.

Have at it, They shatter pretty quick as others have said due to how brittle they are.
I've shot them with everything from 5.56mm to 300 WinMag, no ricochets yet. At 100yds you should be pretty good. One thing I do when shooting steel plates or any other random metal object is to angle it forward (towards the shooting line) that way if the bullet does decide to ricochet it will do so down and into the ground. Just my .02 cents |
