I purchased one earlier this year and at the time I was shooting Triple 7. IF I were going to keep shooting T7, I would see the need. It busts a crud ring really good and takes quite a bit of fouling from the bore. I even tried it after spit patching and swabbing the bore ( directions say to swab first anyway) and it was still removing quite a bit of fouling. As far as wearing out, I think it would after time because it is a brass or bronze scraper. I have tried it without patching since using Blackhorn, but it didnt take near the fouling out and this was after about 20 shots, so I say its probably not near as useful with the BH209.
