    Winchester mod 70 safety catch jammed

    Looking to see if anyone had any similar problem as I have,had rifle out at weekend, hadnt fired it since may so i tried on target and it was spot on,shot a wee stag later on and safety was working fine but when I was out lamping last night I got ready on bonnet for a fox I was squeaking in loaded and went to put safety on but it wouldnt move from fire position so I never took any chances just unloaded and abandoned.Tried to free it when I got home but wasnt moving and I noticed it was uncocking when I closed bolt.
    I put in vice today and pushed sear back and managed to get safety to move but when i put it into rifle and dry fired it again its stuck in fire position again.Its a 3 position safety forward to fire,mid position safe but bolt not locked and fully back is safe and bolt locked down.
    Only thing i,ve done out of my usual routine is after id shot stag and unloaded I put safety forward to fire position and closed bolt on an empty chamber and held trigger in which I dont normally do with this rifle!
    Any pointers would be appreciated
    cheers

    probably just a bit of grit. I recommend taking the cocking peice off, clean it properly and if you cannot take the safety wing off or are afraid to damage it, blow it through with compressed air.

    if that doesn't work, you can only suspect it's the internal 3 position safety sear that's damaged, but I doubt it.

    Not sure of my facts here regarding Winchester safety, but it is common that safety catches can only be moved from the fire position to a safe position when the rifle is cocked.

    ​After taking a shot the rifle will be decocked and the safety will appear to be jammed in the fire position. Once the bolt handle is lifted and the rifle cocked, the safety can then be moved to one of the safe positions.

    If the rifle is uncocking when the bolt is closed that suggests the trigger is mis-adjusted, or perhaps the return spring is weak, or a bit of debris or hardened grease is blocking it from returning properly. You could try pushing the trigger forwards before closing the bolt, to overcome any "laziness"

    Whatever the reason, a rifle that decocks itself as the bolt is closed is unsafe and needs checking out.

    ta for advice and my professional opinion is that its fkd!!!partially stripped it again and pushed cocking slide back to enable safety again and worked it mid to back ok but moving to fire realeases the firing pin which is not good at all.anyone know a good gunsmith with rifle bolts?

    I don't think its anything to do with the bolt. Sounds like the trigger is adjusted too close to let-off, or is clagged up . Its definitely not good, but could be as simple as twiddling a screw half a turn, or a blast with brake cleaner. Get experienced help.

    Sounds like a trigger issue to me. My rifle has an on bolt horizontal safety (a la Win. Model 70) and the safety is only movable when the rifle is cocked. You should be able to let the bolt down to decock fine. If the firing pin is being released you have a problem that requires a gunsmith.

    Hope gets sorted soon.

    I had a similar problem a while ago , and on taking the action out of the stock found that the Timney replacement trigger was loose. There is a screw which tightens up against the bottom of the action, if that is loose, everything fails. Hope this helps.

    thanks for advice, I,ve checked bolt in and out of rifle its the same regardless that as soon as I,ve manually cocked the bolt out of rifle and got safety to mid position it goes back fine but when I move it to fire it releases the firing pin,checked trigger(timney coincedentally)and its all tight so I can safely assume it is the bolt.
    I did google it and it does seem reasonably common in USA the symptoms of mine looks like bolt has to be fully disassembled and metal carefully removed from back of firing pin to allow safety to properly engage again and I aint messing about with it so it will be finding its way to someone who knows what to do this week
    cheers anyway
