A curious thing about the 10/.22 (I absolutely love these Rugers, by the way)... High priced scopes can go bughouse on these rimfires. I haven't quite put my finger on it but it seems like many "high quality" scopes, while made to withstand the punishment of recoil, to not stand up well to the little tic tic tic of the firing mechanism on these .22s. Scopes geared towards air rifles seem to hold up the best. Have also had good luck with Springfield Armory.
