Bought some of these AR500 steel target at a gunshow awhile back, this one, and a couple others next size smaller. This one is rated for .308 caliber rifle, the smaller are rated for 9mm.
I shot my M&P40, M&P9 Shield and the Sig Sauer P238. These targets sure make shooting targets fun. With this bigger target and a pistol, it takes a pretty solid shot towards the top to get it to roll over. In fact, shooting the 380 at 12 yards just made it rock back a little and back forward. The 9 and 40 at 15 yrds could make it turn over.
Of the 3, the P238 was so much fun. It's such an easy shooting pistol, easy to stay on target and even get a double tap on the plate before it can settle back down.
The smaller target will flip with a good hit from a 22 rifle. This particular one is a blast to knock around with a AR.
