BLACKHORN 209 POWDER IN STOCK NO FURTHER A MYSTERY

I've a CVA optima in stainless steel. I even have the black horn 209 breech plug. I load one hundred grains by volume of Blackhorn 209 that has a 250 grain Barnes bullet. I have found that you really ought to use a great primer. Do not make use of the primers designed for black powder as it's not black powder. I use the CCI magnum primers only. Nev
