Maybe you guys can offer me some advice also. I too own a clip fed model 77. I owned it now for about 5 years without any problems. It is cleaned regularly. Just yesterday I took it out for some target shooting with my buddy who also owns a model 77.
I loaded it as I usually did but when it came time to fire there was only a 'click' and no fire... thinking it was the ammo I switched it and same thing happened 'click'. My first thought was the firing pin so I switched it with one my buddy just happened to have (he always makes sure he has at least one extra firing pin for each of his rifles.... lol). Put everything back together but still get the 'click' and no fire. None of the parts look damaged including the firing pin I switched out. Any thoughts? And a big thanks in advance....
