Ruger 10/22 Accuracy Firing PinWider Impact Surface Disrupts the Rim Less, Improves Accuracy Potential Firing pin impact plays a critical role in the accuracy of rimfire cartridges. For example, the Russians developed a 2-pin system that dominated the Olympics. The Casull Silhouette 22 adopted a similar system and dominated IHMSA silhouette competition. The Ruger 10/22 is not suited to a double firing pin, but the existing pin has lots of room for improvement due to it's small, sharp impact face. The problem with too small of an impact face is that it can cut too deeply into the rim of some of the more sensitive (and accurate) ammunition types. Sometimes it can even cut deep enough to cause rim ruptures. We're now offering a more precisely machined firing pin with a full sized impact surface... approximately 3 times the surface area of the factory firing pin. We've been using these without modification and achieved 100% ignition reliability and superb accuracy. What we recommend you do is, install this Accuracy Firing Pin in your Ruger 10/22 and try it. If you get any misfires, you can add some bevel to reduce surface area and make the pin hit a little deeper. The idea is to get reliable ignition with minimum rim disruption. Highly recommended for all 10/22s. Click Here to see ALL of our Ruger 10/22 Accessories!
