If you have a basement, build a bullet trap. Of course, distances to target will be less, but it is nice to just go down stairs and blam away. Don't miss! 1/4 inch plate steel set at about 45 degree angle with 2 by 4 frame. NOT for rifles! Works fine for 38 and a 357 now and then. Great for 22 plinking, daughter shot her fisrt handgun here,(she's a dead eye rifle shooter). I have the bottom filled with 2 by 4's to catch the ricochets but I'm going add a steel bottom, ricochets have a surprising amount of energy. Will add casters with lock downs too, thing is getting heavy. Sorry guys, didn't notice this thread was in long guns, my boo boo. I'll post it over in handguns. .223 goes right thru 1/4 plate steel.
