I picked up one of safebuilder's rimfire targets for a present for my kids a few weeks ago. We have had a blast flipping this target around the yard with multiple rifles and pistols, sub and standard velocity ammo both suppressed and unsuppressed. The target held up beautifully and is a truly great design. The materials are very durable and I'm confident we will get many thousands of rounds enjoyment for years to come.
I highly recommend safeguilder. He's a true craftsman and great guy to trade with.
