I was in a sporting goods store looking to buy some 22's for my Ruger Single Six. There was an older fella working the ammo counter and he seemed to know alot about the different types of 22's. He told me that 22 gallery would shoot great from my gun and save me money in the process. He told me to just clean the gun very well after using the ammo. I bought two boxes of 250 count Remington. When I hot home I looked underneath the box and it says "CAUTION: NOT FOR USE IN REVOLVERS." I am surprised as the man really did seem to know his stuff. Is it common knowledge that you cannot shoot 22 gallery in revolvers?
