[QUOTE="Celt, post: 28900, member: 176"] We have a load that shot pretty good so far with the 300 WSM and a 175GR SMK from a 1-10" twist barrel. The chamber is cut with a min spec reamer with a .3085" parralel throat. Same throat dimensions that the 308 M-852 match reamer uses. Has anyone else had any luck or exopieriance with MagPro powder? These fit and fed flawlessly from an HS 308 DBM modified for 300 WSM [B]NOTE:WE TAKE NO RESPONSIBILTY FOR THE USE OF THIS DATA. THE LOAD WORKED AND WAS SAFE ONLY IN THE RIFLE IT WAS SHOT IN. iT MAY NOT BE SAFE IN YOUR RIFLE. ALWAYS WORK UP TO A PUBLISHED LOAD![/B] Winchester new unprimed brass Winchester Magnum rifle primers 74 grains of MagPro powder Sierra 175gr match King OAL 2.845” Target. Note the rifle barrel is brand new and the group is shot from the bipod, prone with a rear bean bag. The brass was not prepped in any way other than chamfering the neck with a hand held RCBS chamfer tool. No brass sorting was done. powder was thrown with an old RCBS powder powder thrower. The Magpro is a ball powder and meters real well. We pulled a bullet on a Winchester factory load. The powder looked indentical, but really who knows.
