I am fairly sure shorter backs or step bores are more tolerant of underbore. I seem to regularly get paint up to and over .690, so for people like me, many modern underbore barrels are not the best.

EDIT: y'know, I wonder if it 's possible to get different results depending on not just the underbore but the absolute size of the ball. For example a .015 underbore at .695 may react differently than .015 underbore at .680. The forces are not the same (e.g. as far as deforming the gelatin vs breaking it) no?
