Help! Damage to rifle?

Tried a resizing method from the Barnes reloading manual.

1. Screw in die until it contacts the shellholder.
2. Back off half-turn.
3. Resize a case.
4. Chamber case into rifle (looking to feel a mild "crush"). If resistent to chambering, screw die in one clock position and resize again. If chambers too easy, back die out a quarter-turn and resize.

I resized a case per above. I attempted to chamber it. It wouldn't go. I screwed the die down a bit, resized, attempted to chamber it again. It went, although with a bit of difficulty. Not much, but enough that I had to force it a little.

Anyway... tried to extract the empty case but the bolt wouldn't go. I slapped the bolt upwards a few times with the palm of my hand until it went; left a nice welt. It extracted, but I noticed the mouth of the removed case was deformed. In fact, the mouth looked "chewed," as if it had been forced against something sharp (had a small upside-down shark fin etched into it).

I screwed the die down one clock position, resized another case, and chambered it. It went in, although its case mouth appears "nicked."

Question: Did forcibly chambering that tight fitting case damage something? If so, what most likely happened?

Don't know if it's related, but after the above I chambered and extracted a factory round to look at it. Looking at the bullet of the removed round it has a long, noticeable etch mark along its legnthwise axis.

Thanks in advance for your comments/help/advice.

Have you had this rifle a while or is it new and unfired?

Relatively new. I've owned it about 6 weeks. Fired maybe 50-60 times.

I sounds like you have grit in the chamber.
Take a wire chamber brush and scrub out the chamber.

My $.02 worth.

Case needs to be trimmed, maybe?

What caliber? It does sound like maybe it needs to be trimmed.

Ohhh meee. EYESOFTEXAS You have any photos of this case in question??? It would certainly help. Believe me it would...:)

First thoughts from your description sounds to me like a burred or rough feed ramp but I'm thinking your "nick"is on one side of the neck . Is this correct or does it completely encircle the neck? A rough or burred feed ramp would also explain a vertically scratched or etched case.Per previous requests pics would help a lot.
In a discussion with RCBS on a tight chambered Savage I was directed to tighten down the sizing die to where the ram lever had to cam over hard and then adjust back to fit chamber perfectly. Have not had a problem since.

EYESOFTEXAS,

Not likely that you damaged anything, other than your case. I can tell you what initially happened, after that it's hard to tell without seeing the case and knowing exactly how far the die was screwed into the press. The reason why the case would not chamber the first time was because your die was not down far enough to bump the case shoulder back. Most dies have to be screwed down below the point where the bottom of the die initially makes contact with the shellholder. This is called cam over. If you want to bump your shoulder back correctly (.001-.002 for a case fired in your rifle) for long case life, get a RCBS Precision Mic (about $35). This will allow you to set your die correctly so that you don't have chambering issues.
