Re: ammo to shoot steel with
I've been using 1/4" ar500 targets with .45acp for years, at 7+ yards. All that happens is, the impact crushes the lead and shatters the copper jacket lick glass. It makes a flat spray towards the ground and kicks up a little dirt. A loose hanging target is the best so it absorbs alot of the impact and swings away from the shooter. I have targets that are 18" x 24" and 10" squares and they only show a small dimple at close range.
