>308 Rem PSS chamber problem

[drwilca]

I have been working for days this summer to get my .308 loads worked up and have been following this BB regularly. You guys are a great help. Thanks to all of you.
I have my loads ready to go out and group. Lapua brass, Varget,168 SMKs. Fireformed brass, neck sized etc, etc,. I used a Stoney point OAL gauge and bullet comparator to seat my bullets 0.02 off the lands based on this measurement which I find to be pretty repeatable.
I seem to have a long throat - about 0.18 longer than the ogive measurement on Federal Gold Medal match rounds.
After seating my loads I checked an empty case with this COAL and found the case very hard to seat with the bolt. I rechecked the measurements - no error.
Finally I polished the brass of the SMK in the empty case and seated it in the chamber with the bolt - there are no marks from the lands on the ogive - but a set of deep gouges in the surface of the bullet which seem to correspond with the 6 'oclock of the chamber. My assumption is that I have somehow gotten some grit ground into the throat which may have scored the metal? Any suggestion on how to fix this problem?

Thanks

Could you find someone with a Hawkeye borescope to check this out for you ?
That is really about the only way to find out about the grit thing........
If you do indeed have any chamber damage the only alternative is the have the barrel set back enough to clean up the problem....
