I Just worked up some loads in 300 WSM. Shooting 180 Nosler Accubonds, 180 Swift Scirocco, and 180 Barnes Tipped Triple shocks. Have not been able to replenish my Federal 215 GMM primers so I am using CCI 250 Larger Rifle Magnum primers. Tried loads with H-4350, H-4831SC, IMR 7828, and H-Hybrid 100. got 100-200 fps higher velocity out of the Hybrid 100. 64 grains with the Barnes Tipped Triple Shocks gave me 3011 fps average with a 14 fps ES. Shooting a factory Browning A Bolt that I installed a Harrell's radial brake on. Shot several .5 MOA five shot groups at 100 yards.
This Hybrid 100 is a new powder with burn rate between H-4350 and H-4831 SC. Meters well and if it is not temperature sensitive it will be a very successful powder.
