I do have one of their bullseye targets and it works well. I made the mistake of having it up at the 100 yard line at the local range when some idiots showed up, took out their brand new off the shelf ARs and started peppering the 3/16” steel without asking or putting up their own targets. Pretty much ruined the target before I got them to stop shooting at it. I had a friend’s son there using it with his .22 at the time.
They will last forever with rimfire, but at not made to withstand idiots.
Idiots are hard on everything. My dad likes to say they can tear up an anvil with a rubber mallet.
