I broke 1 every 1000 shots or so, so i guess that that is not too bad, but the paint rarely broke on target and it really frustrated me. The shells are kinda cool being clear and all, but the fill was crap. I couldn't see the paint even if they did break. They can be compared to getting hit with rocks too.
The accuracy was to be expected with 32 degree paint. I was shooting the stuff in my Smart Parts All American 16" on a spider compact, with a cyclone 2 bolt and had few problems with it. Probably 1 out of 5 were way off target. I would recommend RPS paint. It's a lot brighter, breaks on contact, and it's made by my teams sponsors. PMI all the way!
