Greener in >>Modern Breech-Loaders<< gives that the 36 bore is paired w/ the 500 Bore Sporting Rifles.

For a 39 bore, the diameter of the plug gauge that would pass the full length was 0.492" or 0.490".

The 39 bore bullet had a diameter of either 0.472" or 0.470".

Is the rifling >>shallow<<, >>deep<< or >>Henry<<?
