Breech Plug Questions
I have the necessary tooling to modify my original CVA breech plug (I purchased and installed a BH209 plug).
What size hole do you put in the face and the depth and also what type screw do you use for the vent liner?
The original plug is sitting in a box of ML parts so it doesn't matter too much if I mess up.

This thread shows one way to modify the QRBP.

In the years that have passed, since the standard QRBP was modified, i have used the CVA Blackhorn plug, and the Western Powders Blackhorn plug, and the modified standard plug. All three work good enough, i can not really tell the difference in their performance igniting Blackhorn. There doesn't really seem to be a compelling reason, to invest in the necessary drills, to do the modification to the standard QRBP. However, if one just likes to spend time out in the shop, that is reason enough.

Put all three plugs in their respected MLs and leave them outdoors (first thing in the morning) loaded horizontally standing, in sub-freezing weather for an entire day and then shoot those three, just prior to night skies.
That's when you may notice a difference in performance level....... or so I was told. The country's East/Northeast is where 80% of muzzleloader shooters partake. More humid there (versus South Dakota) and might be the proper place for that test.

You were told wrong.
What i do to test breech plugs is leave them outside overnight in temperatures -10 degrees or colder. All of these breech plugs will fire instantaneously, the next morning.
What in the world does that mean? Were you typing whilst sitting horizontally?

....horizontally standing....

But if you want to hold the gun(s) all day long, knock yourself out. Wouldn't shock me if you did.

Blackhorn powder will / can get wet and not fire. It doesn't have any shield over it, so water rolls off. The difference between it and others like Pyrodex and 777, is that it can fully recover 100% and not bear any after-effects in velocity and performance.
