I tried them and they were very similar in performance to Federal's Gold Match. Interestingly my rifle (Sako Finnfire) likes PMC Zappers and shoots them just as well as th GM and Eley. The best accuracy was from RWS's R50, but since I do not compete, and the small advantage it provides, it is not worth the extra $. I suggest you try a bunch of different brands, a cheap box may suprise you!
