With the action out of the stock, also make sure there isn't a bunch of crud/rust/whatever clogging up the trigger spring (on the other end of the trigger) also. I've seen that area get built up with years of garbage so that the trigger can't be pulled back far enough to get the bolt to release smoothly.
Don't think it is the trigger spring.
I sort of looked at that this morning just before I had to rush off to work. Spring seemed O.K. to me.
It has to be something with a fairly sharp edge on it to cut/score into the metal on the bottom of this bolt body the way it has !!!
I sort of looked at the front portion of the trigger that you have circled and nothing struck me as really odd but I was in a hurry to get off to work, so did not have time to really take a good look and it and to maybe compare it to the surface of the trigger on the other rifle. I am going to try to take a look at it more closely when I get home.
BUT I am still sort of thinking that someone had been "FORCING" the bolt out of the gun without pulling the trigger or perhaps just not pulling it completely and somewhat dragging that front portion of the trigger/sear against the bottom of the bolt body as it was pulled backward out of the receiver. You would think that they would have noticed these markings that it was making on the bolt after the first few times they did this and realized that they were doing something wrong !!!
Thanks for your help.
