How much bullet release is enough?

I've got a new to me 22-6mm. It had a couple issues I'm working through with bedding, but in examining the ammo I noticed that a bullet will barely slip into a fired case. Measurements indicate about 2 thousandths difference between a loaded round and fired brass.

Is this enough or do I need to turn necks in your opinion to get the best accuracy it's capable of?

I like .004 clearance personally.
Remember brass has spring back also, only one way to know if more clearance is better and that is turn some necks and test.

You don't mention how you arrived at the measurement or how thick your necks are, but I agree with others given the above information. .004" would be better and likely help eliminate some other frustrations in load development.

You could anneal a couple cases then fire them to help your measurements be more precise with spring back. In all likelihood you still only have .0025-.003
