CVA Accura MR QR Breech Plug Project

My MR is very dirty, and in testing i had delays after a lot of shots. I know its because of leakage and shims would fix it. But i dont like shims and i think Lehigh will make a much better reliable plug in the end. But it will take some time and it wont be for everyone thats for sure. If you have no problems and are happy you wont need one.
Now unless you plan on designing a self cleaning BP (an impossibility) I don't see any advantage.

Grouse you're saying you had delays after a lot of shots? And I assume you were using BH209. From what I understand, no matter what BP you're using you will get carbon build-up in the flash hole and it must be removed by hand with a small drill bit. Some recommend this after as little as 10 shots.

Bronko, you will find you get far less carbon build up in the flash channel if you have a good primer seal AND avoid mag primers. I can shoot my Knights and my NULA all day and never need to clean the flash channel. Over 95% of my shots have been with a plain old Win209 and nearly 100% with a standard CCI in the NULA.
Never had a single hang fire, delay or fail to fire ever even after 40 shots. I don't even bother cleaning my NULA plug after a range session. There is almost no carbon in it when i do.
Better internal geometry helps a great deal too and a 1/8 flash channel is not quite ideal. 5/32 has shown to work better in my plugs. All three from different manufacturers. The Savage plug was one of the plugs used to develop BH209 and you guessed it....its a 5/32 flash channel. My Lehighs and NULA are also 5/32.

So you had a Knight with a Lehigh bare primer conversion and basically zero blowby?
Or are you talking about something totally different as usual to get your point across?
