My Wife and I purchased a 3/8" AR500 steel target and shot it with everything from .22 LR to .45 Colt. We shot jacketed, hollow point and cast lead with no problems or damage to target. Today I shot it with my .308. I was using my handloads of 150 grain JSP and according to the load data it should have been traveling at around 2800 FPS. I researched as to how close you can shoot a .308 at this target without causing damage and generally found that at least 100 to 150 yards was needed. I shot it from 100 and it produced a small ding. I backed up to 150 and again a ding was produced. Moved on to 200 and 300 yards and still made a ding. Tried from 400 yards but I was shooting a Ruger Scout rifle with iron sights over a sand bag and couldn't hit it. Especially with 25 to 30 MPH winds. At least that is my excuse.LOL Wonder why this target couldn't handle it?
