I have owned many, many Ruger M77's and you can load a round in the chamber and close the bolt with no ill effect. I have done this for years and it has not effect on the extractor. You might try changing brands of ammo. I have a GSR and it is been a good gun. You can always call Ruger for help; they are pretty good folks.
