Until you mentioned it I never heard of a 6 xc , to be honest i never had a lot of interest in the smaller cartridges but I have had a few freinds with 6br and such , it would nice to have a super accurate little gun to shoot , those 300 gr smk and 90 plus grain of powder can add up pretty quick. Also I am assuming a gun like this would have nil for kick as my kids are into shooting more now. thanks
