Bolt Nose Contact

[bigh]

Should the bolt nose touch the breech face of the barrel on a 22 rimfire? What effect if any does touching.not touching have on accuracy ? TIA

My bolt has a counter bore of .038. To achieve .043 headspace my bolt nose is .005 off the breach face of the barrel. Headspace can affect accuracy. What rifle are you asking about?

Just rimfires in general, I was told years ago by a pretty well known gunsmith that the bolt nose and breech face should not touch.

You were told correctly to my knowledge, there is a bolt nose to barrel clearance spec for every gun I've ever fooled with.
