Why do your 552 missfire sometime?

Answer 1

The Ruger 552, like any firearm, may experience misfires due to several factors, including faulty ammunition, improper firing pin engagement, or lack of maintenance. Deteriorated or damaged primers in the ammunition can prevent ignition, while a dirty or worn firing pin may fail to strike the primer effectively. Additionally, environmental factors such as moisture can also impact performance. Regular cleaning and using high-quality ammunition can help minimize misfires.
