Barrel Fitting Question ( I have read FAQs)

[miller64]

I have read the FAQs and can't seem to find my answer.
Does it matter if the ejector is in while fitting the barrel to a frame?
Does the pressure of it effect the fitting?
Thanks

The first step in fitting a barrel is making sure the chamber face is flat and there's not too much headspace for factory brass, the ejector has to be removed if you do any filing, and its removal does make test fitting a little easier. Ejector removal is covered in the ejector to extractor conversion info in the FAQs. I added that fact to the fitting info for clarity.

Before removing any metal from the pivot, use a flat mill file to make sure the barrel face at the chamber is flat, you'll see metal being removed on the high spots as bright while the low spots remain blue. A little degreasing and touch up blue will restore the finish after you make sure its nice and flat. DO NOT file the breech face flat if a factory cartridge is perfectly flush with the barrel face, doing so will cause negative headspace and the chamber will need to be reamed a bit by a gunsmith. But if the face of the cartridge is slightly recessed below the barrel face, you should file the barrel face to true it up and reduce the built in headspace caused by the uneven barrel face.
