I'm just getting into reloading, and my Sendero in 7mm Rem Mag currently shoots best with HSM Trophy Gold ammo with 168 gr Berger bullets. It beat out the Winchester ammo I've had as my best up until this year. I was wondering if anyone has every taken one apart and recognized the powder and/or primer components are used in 7mm HSM ammo? If so, would you mind sharing what they were? I'd love to make an exact copy of the factory ammo as a good place to start with my reloading. Thanks for any input you have!
