You think that 20/1000" is worth considering and I think that 20/1000" is worth considering, but a lot of people are screwing Savage and Savage-specs barrels onto XL/XS-7 actions and going on their merry way when they feel friction against the bolt.
I've been trying to point out to folks that different in the depth of the bolt face recess MIGHT be a problem, because the friction that they are feeling MIGHT be the back of the barrel against the front of the bolt, not the rear of the headspace gauge against the bolt face. With 20/1000" you are going to get case stretch, but how much stretch is there before the case separates? When I realized that the difference in bolt face recess might cause a false "proper" headspace feel, I trimmed my barrel back and recut the chamber.
