Match .308 Reload Chamber Issue

[Vamike9]

Hey guys, recently I reloaded some once fired Match .308 ammo and noticed a chamber issue.
I neck sized the cases as they were only once fired in my rifle. I first seated the 168gr Amax COAL to 2.800 then 2.750 to see if that changed anything but it didn't.
The empty brass cases I've yet to seat all chamber easily but once seated they are extremely hard chambering and leave a mark. Picture below...
Any help would be greatly appreciated as I don't know what's going on?

You might have a burr in the throat, get the barrel scoped to be sure there are no burrs in there.
It's definitely not from the rifling, what type of action is it?
Any action with a plunger ejector can force a cartridge hard into the side of the chamber as it enters it. This may be causing the problem.

Cheers.

It's a Remington 700 Milspec that's never given me an issue before now. I've loaded at 2.800 before with no marks but this is the first time I'm neck sizing.
Still, empty brass chambered fine until bullet was seated. Thanks for any help you all can give, I sincerely appreciate it.

Is there a foreign object in the chamber of your rifle? I had a piece of a broken extractor in a chamber once.

Good luck

Thanks everyone, apparently the shoulder of my once fired reloads was too bigh. FL sized them and no issues.
