Fuzzy, haven't tried the federals. Just got back from the range with my .22 Mag and my .17 HMR. In my .17 HMR the Hornadys shoot the best with the Remingtons in second place. If I had to shoot or hunt with the Remingtons I guess I could, just have to re-rweak the POI a bit and settle for a bit larger groups, but not by much. The CCI's I just used up as a noise maker and to help season the barrel, they dont shoot in my gun. I would like to try some Federals and have heard there are some 20 grain .17 MHR shells in the offing, anyone out there got any info on them?....<><.... :grin:
