Great project and it is really neat that you have the talent and the tools to complete this project... wish I did.

I have a couple of comments, I somewhat disagree with your thought about the powder needed to ignite BH. I think you already no I usually go the opposite direction and install the 'flash hole' at the end of the breech plug. I prefer using the inverted cone shape of the Lehigh Vent liner for the project. The inverted cone is important in reducing the blow back pressure from entering the breech plug and up against the face of the primer.

I have been using using a converted breech plug in a couple of my ML's for some time now. Shooting BH with it is not a problem even using a older Remington 209-4 primer, which I believe is the coolest primer that i know of. I also use Win T7 primers and routinely use Win W209 primers.

This is what my conversion looks like



If you look at the last picture in the display you can see the Knight brrech plug is a lot longer than the CVA plug.

Do you have any Lehigh vent liners? If you do and sometime if you in the mood make one of your plugs but install the liner on the end and see if it works as well for you as it does for me.

Here are a couple of CVA plugs that I converted some time back... The one on the right is my best theory. And then if you add your abilty to head space the plug (which I did not do) it would IMO be a great CVA plug.

Western Powders is besides themselves with the problems that are inheirent to the CVA plug. To the point that they alter CVA plugs and pass them on to CVA users so that they might get a more reliable BH shooting CVA.




This drawing kinda explains my theory... but you know theories they are normally good and justified to the person that presents the theory



Hope some of this makes sense to somebody other than myself....
