I have the same problem with 303 and 30-06. I never thought it would pop holes with lead bullets. Im trying to get my hands on some Armor plate so I can use the targets longer. 30-30 and 44mag will bend 3/8 steel plate
This was actually hardend steel, it is just a tad stronger than the mild steel targets I have, no comparison to AR500. With AR500 you just don't get the nice splatter effect!
