Re: winchester model 77 malfunctions
There's a bunch going on in the Winchester 77. There is a firing pin, a firing pin striker (both of which have springs) and a mainspring. The problem could be with any of these. The problem could also be that the cartridge is not going fully into the chamber and the firing pin energy is being spent pushing the cartridge forward instead of denting the rim. May just be a cleaning issue and making sure the chamber doesn't have burrs.
That is something we would duplicate on our test range, then pull the rifle down on the bench for repair. No point in buying parts until you know what you need to buy.
