    What powder and primer used by HSM in 7mm mag 168 gr Sierra BTHP match

    Does anybody know what powdrr and primer HSM is using in the 7mm rem mag 168 gr BTHP match set up? They don’t have any available now. So I’m looking to make some. I know the bullets are Sierra Match Kings and brass is Winchester.
