As a person who has shot the Bh209 but prefers other powders I would like to suggest another point of view and I am far from a CVA person.
It's kind of like which came first the chicken or the egg but some might think of it as "Why would a company put a substitute powder on the market that has well known ignition problems in a lot of the guns that are out there?"
It is pretty self serving for a powder company to say it is the gun maker's responsibility to make a gun that works for THEIR powder.
Just another point of view from me.
