Proof pre-fit chamber issue.

Nope! i completely cleaned the chamber and inspected it and i can't see anything.
So I am understanding that the same ammo worked fine then it just would not chamber?
Did you try different ammo?
Can you insert a fired round into the chamber?
Check the ammo look if the neck/bullet is concentric maybe they were damaged / bent.

fired case and go gauge fit fine as shown on the picture on the original post its grabbing the bullet. That is what i dont understand its like a bur just popped up out of nowhere. shot 2 rounds fine then i couldn't chamber the third.
Did you try other rounds? Did you compare the one that didn't chamber to anything else in the box?
Any round i have tried 2 different kinds of hornady and federal its not a ammo issue......... Its a 6.5 creed.
The thing that is weird to me is it shot find for a couple hundred rounds and then all of the sudden had issues.
CLR the chamber end up through the throat then hit it with a brush (brass/bronze, not nylon). Probably have carbon build up or carbon ring that's catching the bullet.
work it over yesterday with some solvent and a very mild polish and got it working i guess time will tell if it keeps working. Still no response from proof im not gonna shoot it much till elk season is over.
If it was a really nasty carbon ring, which is sounds and looks like it was, it doesn’t have anything to do with Proof or who ever chambered the barrel.
Not directed at op, but this is why I laugh when someone talks about not cleaning their bore for 5-700rds....good luck with that carbon ring.
OP, glad you got it sorted, couple hundred rds is kinda fast to get a carbon ring. What ammo was it?

Reamer wear is a thing that happens, too. The free-bore on the Creedmoors (and most match chambers for that matter) is fairly tight to align the bullet straight with the barrel. It doesn't take much wear to get them cutting on the tight side of things.
actually got a response from proof and i told them what was going on and they said if i had any more issues let them know.
Looking at the pictures of the throat of the chamber area.....that one/two grooves where the reamer cut in the throat look like it cut really deep on one side.
Bore scope the whole throat area and rotate the bore scope around to see if the reamer cut evenly all the way around the throat area of the chamber. If you see where it cut in the grooves in one or two of them but the other grooves are not touched then the reamer/chamber job is off center.
I could be wrong just looking at one or two pictures but it’s worth checking out. Other things not known are what the reamer is spec’d at on the throat and also what the groove size is of the barrel. All could be fine and the picture is just misleading.
