I just bought a ruger 10/22. I have never owned a 22cal rifle before, and never had this problem with any of the larger rifles or shotguns I have helped clean. I bought the right size jag, patches and cleaning rod. In fact I have tried two different kinds of patches. But no matter what I try, i can barely get the patch through the barrel when I clean it. In fact, I bent the cleaning rod trying. to get it all the way through the barrel i have to tap it with a hammer. The guy at wal mart told me to just use one of those little patch loops, but that doesnt fit tight enough or even enough to do much good. What am I doing wrong?
