Myself, i don't believe it is the size of the flash channel that differentiates between a reliable plug for use with BH, and one that isn't. Most plugs that are made in USA have a 1/8" flash channel. Some of the plugs made across the ocean have a 3mm flash channel. That is 0.125" and 0.118". There have been many many many times when the flash channel of my USA plug was closed down to 0.063" or less, and it just kept right on igniting BH.
There are other differences between breech plugs that are more important to determining whether a plug is reliable with BH or not.
