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.
