Speaking to Savage rifles, I don’t remove the ejector, never have. Leaving the ejector in does not mean your going to have 6 to 10 thousands headspace, if you have and mechanical feel at all. I don’t know what My headspace is, but it couldn’t be any less.

lately I have been disassembling the bolt to try to achieve minimal bolt lift.

It is also a precise method to find the lands with zero resistance on the bolt.

Those who feel more comfortable removing the ejector or anything else, no problem, go for it.
