It is something worth considering. Hadn't heard of ricochet issues with bowling pins, but could see how it would happen. I've been surprised at the Action Target Plate Rack that I purchased last year. There have been a couple thousands rounds shot at it from 22 lr. to 10mm Buffalo Bore loads--at the recommended 10 yards no-one has been hit by anything. Although I've found bullet fragments all over the place.
It's a damn good idea to wear safety glasses. I've heard of riccochets like rost mentioned, so it's something to be mindful of. We've never had any issues, but we shoot them at 35 feet instead of the usual 25 and our tables slope to the back ever so slightly to help the pin slide back off the table better. That may also help to minimize riccochets back to the shooters.
