I have a Ruger Mini 30 which has a Garand style action which I am sure most people here know. Lately, I have noticed the firing pin is a little sticky in the bolt. I think it is just gummed up and not a bent firing pin, I have only fired ammo recommended by Ruger, no ammo with hardened primers etc. Does anybody here at the sight have any suggestions how I can clean it short of taking the bolt apart? I hope to avoid the dreaded slam fire as could occur with a stuck firing pin
