Ok so I have put together my first build. I have a criterion lite varmint 300 mag barrel and I used Forster go/no go guages to set headspace. Keep in mind this the first time I have done this. When I put the guages in my bolt would not extract them I thought maybe it was just the guages so I put some cartridges in and it won't extract them either. The case just stays in the chamber. What did I do wrong?

Are they not extracting because they are stuck in the chamber? Or are they not grabbed by extractor?

I don't think they are grabbed by the extractor because I can tilt the gun back and the cartridge falls out.Quote:

Well I didn't take apart the bolt when I set the headspace. Is that my problem?Quote:

Possibly. If you stopped screwing in the barrel before the gauge reached the bolt face, then it's possible that is the reason. I have set the headspace on almost all of my builds with the bolt head fully assembled. It hasn't been a problem, however I was always sure the gauge was snug against the bolt face and was extracted by the extractor.
I will take everything apart and try again

When you try to close the bolt on the no-go gauge, will it extract it?
The extractor most likely did not go over the rim of go gauge, head space is excessive & needs reset.
That is what the problem was, I took everything apart and put it back together and it worked fine.Quote:

I love a happy ending! :becky:
I'm glad you tested it so thoroughly before firing that Win Mag! On the off chance the firing pin hit the primer, that could have been very dangerous.
No chance I was even gonna think about pulling the trigger unless I was confident it was put together right. Gonna try it out this weekend I can't wait!Quote:

Put it on a rest with a sandbag lying on top. Attach a long string to the trigger; load a round, back up as far as the string allows, then pull. :p
I find that putting a primer in the case and trying it that way is a safe way to test fire a rifle. Take all that string and throw it in the brush pile.

But to answer your question, a light or no primer strike might be an indicator of poor head space.

Moving the shoulder forward....Not in my rifle.
Lucky for him it would never have hit the primer. I takes quite a bit of force to get a case behind the extractor. That's what the lead in chamfer is in the receiver for. In the op's case, it never had the opportunity to do its job.
