Purchased this rack for my Gun Club. We run Centerfire and Rimfire monthly steel plate matches with static steel, pepper poppers, Texas Star etc. Assembled this and tried it last night. In upright position the Rimfire hits were tough to see. Being 3/8 plates I expected that. Using 9mm, some plates when hit off to the side would cause that bracket to twist on the 2x4 and not go down.
The hanging position is where this really shines. Reaction with 9mm was good and even Rimfire hits could be seen, making scoring easy. Will be ordering a second set.
