This might just be my observations, but on the plates at our club, the worst seems to be .45acp, followed by .22LR. I agree with those that have stated that plate condition makes a big difference in ricochets. Poorly maintained plates, especially those with deep craters really introduce random splash and rebounds. We spend a lot of time maintaining our general plinking steel targets at our ranges, and use a separate, fairly pristine set for SCSA events. So far, it's worked well.
