Got some personal land now that I am able to shoot on. Been looking at some different ways to set up targets and want to get some steel targets. The issue is I don't know much about them. I want to be able to shoot pistol rounds for close range but rifle rounds up to 308 with some distance. So my question is how thick do the targets need to be. Can I buy sheets and cut them myself since I have a buddy with that capability. Also where is a good place to buy some.
