So I have a dilemma......
Tonight I bought a rifle which took me a long time to find. It's in the caliber I've been looking for...the wood quality I've been wanting and control round feed action.
Its used... barely used. The gentlemen I bought it from is a respected man and I trust him.
Well I got it home in better light and discovered the bolt face has a hear line crack. Barley noticeable but there.
I phoned him and explained my discovery, he was quick to say bring it back and well sort it out. He was as shocked as I was.
The rifle is a Kimber 8400 in 338win mag with absolutely stunning furniture.

Now I'm not a gun smith. So my question is.....
Can you replace just the bolt face on a bolt?
Or do you replace the entire bolt?
Are bolts tailored for each individual rifle as they are manufactured? For ideal head space?

Would you just return it?
Or pursue a bolt on the sellers dime?

Appreciate any input.
