[QUOTE="GMB54, post: 5224335, member: 15365"] Thats absurd. Every single time you fire your ML the flash hole gets a tiny bit larger. The flame erodes the flash hole with each shot. The FLASH CHANNEL needs to be cleaned with the correct sized drill bit by hand. The flash channel in a CVA and Western powders BH209 plug is 1/8". The hotter your primer and the more that primer leaks the faster it fills with carbon. Clean it out using a bit within 15 shots and it stays pretty clean and far more reliable. [IMG]https://i.imgur.com/ejGIRDN.jpg[/IMG] The real trick to BH209 is use a primer that seals very well and use them in a well designed breech plug. The CVA plugs have a larger OD primer pocket and sloppy head space. You can improve the fit by using a fatter/longer primer like the Nobel/NSI and/or shimming either the primer pocket or the firing pin bushing to get a slight crush on the primer. About .003 crush is the right amount on a break action. [B]Just put in a new primer and close the action without firing it.[/B] If the primer is .003 shorter then you are in the zone for primer crush. I prefer shimming out the firing pin bushing because you maintain more primer IN the primer pocket. Lots of people though have great luck using a shim or o-ring in the primer pocket.
