This is a super simple and effective way to hang steel on t posts. I've made a handful of trips to the range and used this hanger and it's really easy to use and holds up great. The last few times I hung a 25% IPSC at 600 yards as a 'truing' target and it held up just fine to impacts from 6.5 Creedmoor, 6 BRA, and 308. Another positive is that I use this hanger as a template to paint chevron center aiming points on my steel targets. The only con (if you truly had to find one) is that you have to have to flip the t post flipped around compared to how they are oriented with my other JC Slotted hook hangers get the steel facing the right direction. Big deal? No, but might be annoying if you're working with a public range that has dedicated t posts or something.
