I had my bore mike set at the Rock Mountain's Northern SxS in July and Rich was kind to let me measure the bulges. I have the numbers here somewhere but haven’t been able to find them as yet, but I distinctly remember both chambers were uniformly bulged and within a few thou internal diameter of each other. Apparently both shells were loaded to the same pressure level.

A somewhat similar but happier incident happened with newly imported 28-gauge cartridges at Hausmann’s in June. As told to me by a Model 21 owner he stopped firing and returned the shells to the vendor when his 21 was hard to open
