Fouling will also slow down or “bind up” moving parts, possiblyresulting in misfires (failure to fire), and “hangfires” (firing delayed up to a fewseconds). It is, therefore, important that your RUGER ® MODEL 77/50 becleaned thoroughly and without delay after each use. Furthermore, Black Powderfouling promptly hardens with the passage of time making disassembly difficult,and this fouling is extremely corrosive, even to stainless steel.A firearm must be free of rust, dirt, grease and firing residues to function safelyand reliably. Periodic maintenance, which includes inspection of components todetermine if they are in proper working order, is absolutely essential.27
