I have found several, probably close to 50% of the pellets shot at this steel plate, on the ground flattened like coins from the impact. Finding them, at most, 5-6 feet from the target after hitting both flat and pre dimpled sections, I'm not worried about them ricocheting back at me. I shoot between 20-30 yards away right now, I've even stood only 10 feet away and shot the plate just to see if it could penetrate and i still wasnt hit by a ricochet, I found the flattened pellet only a few inches from the base of the plate which sits on the ground.
Also, it's just what I had laying around. I am currently out of work and so I dont have the money to buy targets, even the cheap paper one's which don't help with accuracy or sighting in a scope. Generally, I prefer to use the stick-on reactive paper targets when shooting, but again they cost money I don't currently have. I had the steel plate and plenty of spray paint laying around from previous projects last year when I still had my job. The steel was originally the base plate for a tire rim fire pit I had built.
Plus I don't mind the dimples, at any time they become more shallow than usual without taking longer range shots, I know something is wrong with my rifle. Same if the dimples become deeper or the round penetrates the steel. Though I'm not worried about over penetration as I have the plate propped against a 2x6 pine board against my shed door. I have shot the shed door directly just to be sure and it stops the round without so much as 1/8 inch penetration.
