I am tring to find a load for a 210 SMK in my .308. It is a Savage target action with a 1/10 McGowen. The barrel is throated long enough that the bullet can be seated out without the pressure ring going below neck shoulder junction. The action has been timed and trued by Fred Moreo of SSS. It is in a Brux aluminum chassis.(yes I said Brux!) I have most powders available. Brass is Lapua, weighed prepped and neck turned. Bullets have been sorted , trimmed and tipped. All charge with a PrometheusII within .010 of a grain. Seated with a 21st Century Hydrpress at 24to26 lbs pressure. Using .002 neck tension. Just can't seem to find a load that will group or show good chrono results(Magnetospeed) any educated info appreciated.ounts and rings are tight on a 10-50 Sightron action screws torqued to 40 in Lbs.
