You're the one that writes that one needs at least a 5/32 flame channel, and a 0.032" flash hole. The appearance of the plug after 24 shots, more or less verify what you write. I haven't cleaned the rifle or plug yet, but i did test to see what size drill, would fit into the remaining opening........1/16".
It is also conceivable to me that the primer seat in this breech plug wouldn't have been ruined, had the flame channel been 5/32", and the flash hole been 0.032".
What ever; the breech plug as it is, ignites BH in sub zero weather, and when it is nearly plugged up with carbon.
Another thing i wonder is, would i get better results with 130g BH, if i had a larger flame channel, and a larger flash hole.
The Lehigh vent-liners go threw a process that keeps them from wearing out from the heat as well as hardened. I'm pretty sure it's not all about hardness. You stated you got 100 shots and no wear at all????? That's dam good in my opinion. Are they cheap or expensive?
As far as the breech plug, not sure if that would help. I would say no, clean plug against clean plug. The more you shoot my theory and others would be more consistent i believe.
