Parts ID Winchester rimfire bolt

[trevj]

I have a complete bolt assy I am trying to put a positive ID on. Looks to me like it's for a Winchester 22 levergun. Model 150/250, as best as I can tell.

Aside from being filthy, it has one pin hole blown partway out, middle of second picture.

Anybody recognize?

Cheers

I have a model 250 and the bolt looks like that. I recently had the firing pin replaced on it and now the rifle won't chamber a round (without effort), extract or fire!!! I guess I'm not putting the bolt back in the rifle properly.

Basic troubleshooting.

Does the action cycle smoothly without ammo?

Does a unfired cartridge drop smoothly into, and shake out of the chamber, while the bolt is removed?

If the cartridge does not drop in freely, look at the chamber. It could have had a dent peened over that hangs up the cartridge. If the chamber shows signs of the firing pin striking the edge of the chamber, have a good look around and see if you cna figure out why.

From this bolt, the pin protrudes at the back of the bolt, about the thickness of a new style penny. I measure it at .053" (the penny measures .056"). That's for the bit that the hammer strikes, not the 'tail' of teh firing pin.

Good luck!

Thanks for the Ident help, too!
