I am having outstanding accuracy and velocities around 3120-3130fps using 83grs of H1000, win brass and Rem 9 1/2M primers using the 165gr Sierra HPBT. Low extreme spread and low deviation. (please start at 80grs and work up but I am showing no signs of excessive pressure in my Savage). This is a compressed charge filling the case just to the bottom of the neck. It posses no problem when loading.
