Thread: Winchester model 70 3 position safety problem

@Rated M for Magnum.I think you're on to it about worn/machined cocking piece or sear. To my eye, I admit I've had a couple of bourbons with meal, the surface on the cocking piece in top photo looks to have been filed/stoned at an angle at some stage allowing the firing pin to go too far forward for the safety cam to re-engage properly. Build the surface up and reprofile correctly.Take note of the engagement angle, it's important to match sear.It won't be that difficult, the steel isn't as hard as you would imagine.
Just my 2 cents worth as a long time owner of model 70's.
PS. What calibre is it, could be interested if for sale.
