Im thinking about getting this thing for all some of my handguns. 22LR, 9mm, .45, 357mag...
Now say I set it up at 15 yards or so will it be a risky for me? will it be possible for the bullets to bounce back? Maybe people that use metal targets can help me out here.
I've got that one (Birchwood Casey) and the smaller one for .22s, and I say, save your money. They don't work very well - sometimes yes, sometimes no. But you have to have them set up and angled *perfectly* for them to flip up without "knocking through" and coming full circle back down, and yet at the same time not be stopped so well by the top that the top will actually release the other 2 when hit. I don't have 30 minutes extra at the beginning of each range session to spend downrange (making everyone else wait), while I hammer & tilt & kick the dirt, trying to set them just so. If I were you, I'd instead get a dueling tree - there's a brand they sell at Sportsman's Warehouse that looks very well made, and not too pricey.
BUT, having said that, it appears as though they MAY have improved the design, such that they work better now - dunno - but buyer beware.
You don't have to have two people to use a dueling tree. Just shoot them to one side. Then shoot them back to the other. Much more positive of a "reset" mechanism than the type I have and you linked to.
I've built several types of targets. Spinners & shilouettes are my favs. 3/8 mild steel for 22,9mm,40,45 Hard steel, Truck frame, for 357 & 44 mag. If you put a forward tilt on the shooting surface, the bullet splash is deflected down, but I still stay 15yrd back. Heres a pic of my typical shooting range set-up. The shilouettes have 3" bulls that flip up.
