Re: Fun stuff to shoot at.
I have a dozen steel plates that stand by themselves on bases, set them up in rows or alternating with two partially hiding a third one and shoot to knock them over. We use 1/2" pieces of steel, 12 to 18" square, have two pieces of angle iron welded on the bottom to make an upside down T so that they stand by themselves. Really good practice, we don't shoot them closer than 700 yards and they will last forever. If you set them up in dirt and they don't want to fall over then just put a pebble under the front edge so the plate leans back a bit, then it will go over. Make them smaller if you are shooting closer, and thicker or of hardened steel as they will get beat up.
We have some of these targets drilled so we can hang them from chains on the target frames, also stand them up on top of our big frames so that they get knocked off, lots of stuff you can do if you have lots of targets.
