RimVsCenter is an informational and educational web app tool used by conceal and carry instructors to teach students about the difference between rimfire and centerfire ammunition. What the site is displaying is strictly a comparison between the two ammunition types and are in no way affirming one ammunition type superior to the other. Both ammunition are lethal and should be treated and used with upmost caution, awareness, with upmost respect to life and law. We are also extremely supportive of gun safety through best practices and smarter regulation.
