Not to discourage anybody from tring bh 209 but i tried some 209 in my krb7 and thepowder was 5 months old, i properly closed the container last time i used it,took it out on the range 2 days ago and had trouble with fire hesitation and shooting low and sparatic....wasnt consistent at all.it was a damp cold day though so im giving it another go with the krb7.
Welcome to the forum. I think your trouble might be in the choice of rifle. As the KnightRolling Block design of the breech plug was having some issues with BlackHorn 209. They were getting hangfires as I remember.
