Stiff Bolt Turning New Gun

[DoneNOut]

New Gun, new sized brass, bullets off the lands. Clean chamber and brass. Bolt rotates with stiff chambering. Even tried bumping shoulder back no change. Is the bolt face too long? Pushing the case hard against the chamber?

You might have a burr in the bore just after the neck

Is this a custom gun?

 

[Starlite]

A borescope would answer the burr question

BFD, check both action screws for protruding too far into the action. May show a mark on the bolt lug. The make and model wasn't mentioned, but I've seen this occurrence on a few actions.

I'll give that a look thanks. However, its slick as snot without brass in the gun.

Are you measuring your bump with a comparator?
If you are take some measurements at the .200 line on new brass and fired, do the same at the shoulder.

I do measure the shoulder bump on all my loads, however, This is happening with new sized brass. Haven't even fired the gun yet

Any marks on the brass when you chamber? Mark the brass with a black sharpie at the .200 line and shoulder see if its rubbing and were.

I can spin a case freely inside the chamber. I think the ejector might be too tall or front to back bolt lugs too long.

 

[L.Sherm]

Snap a case over the ejector then try and chamber it.

When you dont have your die adjusted down enough to actually bump the shoulder you make the cases longer because your just squeezing them. Make sure your actually bumping the shoulders back.

Couple things:

Did you check the length of the cases?

Can you push the Ejector plunger down flush with the bolt face?
