My M77 in .257 Roberts suddenly developed a problem where the bolt does not want to slide to the rear/full-open position.
From a closed position, lifting the bolt and attempting to pull the bolt back = fail. wiggling the bolt sometimes works. More reliable is partially closing the bolt, then lifting it up again, after which the bolt pulls back easily.
Any help or suggestions are appreciated.

A good .30-06 is a 99% solution.

Are you able to remove the bolt?
It sounds to me as if there is a piece of debris rattling around back there that is getting wedged between the bolt and the receiver.

Try opening it with the floorplate open and spring and follower loose.

Try opening it with the floorplate open and spring and follower loose. No difference. Next step will be to remove the trigger group.

Perhaps you have the tang screw that is either too tight or too long and as the bolt is withdrawn, the bolt drags on the tang screw causing the problem you relate.

Update. I tried my M77 .30-06 bolt on the .2257 Roberts. No problems, which I consider a good thing.
It appears the extractor is somehow hanging up and preventing the bolt from being moved to the rear. If, from a closed bolt, I open it up all the way and press down on the front of the extractor, the bolt slides out freely.
Can't see anything wrong which means I can't fix it. Sending the rifle back to Ruger unless someone comes up with an idea.
Thanks to all.

I just posted this elsewhere.....  Check for receiver torque. Take the metal out of the stock and try the bolt. If it works smoothly, you need to glass bed the receiver into the stock flat....
