And a valid thought. Let's think of it this way as well: BH created a product which has produced results a lot of ML shooters were after. Mainly the ability to not have to swab between shots. If it were only that component alone, (which it's not) the powder would probably still have a good following. We know that BH is selling a lot of powder even at the higher cost per shot. So yes, they may have created a powder which only works with certain designs, but ML shooters have dictated by the large consumption and approval of the powder, that they want a gun which it works well in.

Regardless if BH was arrogant (for lack of a better term) in creating a powder that doesn't work well in all guns, they have created such a following with the product, it would now be the wise decision of the gun manufacturers to produce BPs that work with BH.

Another thought: I can't recall a time when I heard someone say, "My BP works great w/BH but not w/Pyrodex, 777 ect" So why would CVA not want to design a plug that allows shooters to use whatever powder they choose? Instead, now if you purchase a CVA it may or may not work with the powder you want to shoot.
