About blackhorn 209 powder in stock
I have a CVA optima in stainless-steel. I even have the black horn 209 breech plug. I load a hundred grains by volume of Blackhorn 209 having a 250 grain Barnes bullet. I have found that you really should really use a superb primer. Never use the primers designed for black powder as this is simply not black powder. I use the CCI magnum primers only
