Bolt Locking Lugs

[musketjon]

I have a 1916 BSA No1 MkIII* and the bolt number does not match. I was doing a bolt test last night and only one of the lugs is making contact. I haven't shimmed the offending lug yet to see how much gap is present. Is it ok to lightly stone the "high" lug until both get equal engagement? I know to only do a few light strokes and check. It's labor-intensive, I know. I just don't want to cut through the hardening on the lug. I know head space may be affected as well.
Thanks
Jon
