Using pressure on the stripped bolt with a cleaning rod down the bore & pushed against something solid while you slowly operate the bolt can sometimes allow you to 'feel' setback.
Kinda shade tree, but at least it allows you to check something while waiting for gauges and indicators to actually measure for the real thing.

Does your 03 Sedgley rifle have two extractor cuts on the bbl instead of one?
That's a good trick - I'll try that. And I've never counted the extractor cuts - I'll check it out. Would a second extractor cut be from a prior "campaign of restoration" (as Wallace Gusler would call it)?
