Factory rounds sticking?

I've got a 6 Creed that all of a sudden won't chamber factory 103s. I've shot hundreds of these rounds, some even from the same box that now are sticking bullets in the rifling. They're so stuck they'll pull out leaving an empty case and powder all over the place when I try to extract a live round, and the bullet is lodged… though it doesn't appear to be engaging the rifling. It's acting like the rounds are too long, but they're measuring ok.

It seemed to happen suddenly, and a good scrubbing of the bore didn't change anything.

Could it be a nasty carbon ring?

It's just weird, because this rifle has always been flawless. Barrel is a 1-8" Benchmark with about 1500 rounds through it.

Thoughts?
 
The above posts got it right.
Just went through it 2 weeks ago. Ammo was hard to load and stiff bolt when shot. Bore scope showed a perfect carbon ring that was so thick it allowed gasses to bleed back into the chamber. Took a couple of hours to get it back to bare steel and shooting great again.
Used chamber brush and Iosso to get back to shinny clean again
 
You will want a good carbon cleaner, and some elbow grease and time. I've not used any of the products mentioned, but I'm sure they work just fine or folks wouldn't be recommending them, Bore Tech Eliminator, and ThorroClean are a couple more if you can't find above cleaners.
 
I had this same issue with a Howa Super Lite in 308Win. Had heavy bolt lift with Federal Nat'l Match. A good chamber scrubbing solved.
 
Without using a borescope, you'll never know what you are really dealing with. Hardened carbon, build up over 1,000 rounds, is nearly impossible to remove without a heroic effort. Your progress in removing any/all of the carbon will require a periodic view through the scope.

I have one rifle with a high-end custom match barrel that just builds carbon. I clean it regularly and occasionally run some Isso or JB short-stroked through the bore. Despite all of my efforts, the borescope still reveals carbon in a few places. Even soaking the bore for days with BoreTech Carbon Remover did not resolve the problem.

If there is a single reason to clean your bore regularly and thoroughly, it is to avoid a carbon build up that gets heat treated over time.
 
I've upped my cleaning frequency after doing battle with a carbon ring in my 7mm Rem Mag. I put a patch around a brush, soaked it in Carbout, pushed that in so that it was on the ring, and waited. This was after an extensive cleaning regimen. I've also used CLR but there are some barrel mfg's that will void your warranty if you use it. It was faster than Carbout

Mike can you use Carbout with a blued gun? Or just stainless?
