Anyone on here shooting BH209 out of a an older CVA break action? I have the optima pro and was thinking about switching to BH209. I have the prior 2010 version before the quick breech system that now offers a breech specifically for BH209 but will not fit my older gun. I have seen where people have modified the breech by drilling out the flash hole, but I think this is mainly for cleaning out the carbon. Any ideas?
