Just got my 20br together and finally had a chance to shoot it. It is very difficult to extract fired cases. Even at 28.5gr Varget under a 55gr Berger it is more difficult than I have ever felt. Todd Kindler told me this is a very very weak load so it should not be a pressure issue. Sized cases cycle fine. The only measurement I see a difference between sized and fired cases is about .002-.003 shoulder bump and the neck goes from .233 to .235 in a .236 chamber. I am at a loss.

Don't pay any attention to what Todd said, you have a pressure problem. It could just be a hot lot of powder. I would check velocities on a chronograph and compare to acceptable pressure data. Every barrel has a personality of it's own, it may not like the combination you are feeding it.

What action are you using?

It is a Savage target action. Problem still exists at 3440fps which is pathetically slow. If this is how it is going to be I am going to sell it or part it out and build something else. This is not acceptable.

Is this the first barrel you've had on the action?

Yes. I had Sharp Shooter Supply time and true the action and install the trigger and barrel.

Check out the chamber with a casting of Cerrosafe......... that will show any problems in that area..
How does the brass look when it's extracted ?

The brass is scuffed up more than I think it should be.
