Two quick questions for the people in the know..
1) All else being equal, accuracy in a rifle closing on a NO-GO gauge but not closing on a FIELD gauge, as general rule, will be worse compared to the same rifle not closing on a NO-GO gauge? "Excessive" headspace will impact accuracy? In what expected amount, in terms of MOA (if it can be generalized that way)?
2) What is the best way to check for throat erosion?? What are the visible signs to look for, if any, with a regular borelight? Many gunsmiths do not have special tools for throat erosion check...how they do it??
When I check a firearm barrel, especially if can be inspected from the breech, I try to look for any surface irregularity, rough spots, etc..
Thanks!
Regards
