Over the years I have never given a thought about .22 rifles. I have just finished the book "One second after", and have changed my mind. Just asking about the different chamberings for .22's. Will all rifles chambering for .22's take these different types. Will a rifle in .22wmr also take .22 short and .22 lr. Please excuse my ignorance, but as I said a .22 never entered my mind until I read this book. Now I feel the need.
