I have found about .002-3” difference in headspace between them. I have heard from more than a few gunsmiths that almost all similar action manufacturers will have similar tolerance he between actions, despite their claims of +/- .001.
Yep.002 spread which really isn’t that big of deal unless you’re at the edge of limits already.Saying +/- .001" means it can be .001" above or below their desired measurement, which creates a .002" window. Am I missing something here?
