[QUOTE="MarkA, post: 1638747, member: 5220"] I'm using RL26 at 68 grains with the 140 grain bullets with speeds at 3,285 if that helps base line at all. Fed 215 primers and hornady brass 24" barrel. Cartridge : 7 mm WSM Bullet : .284, 140, Nosler AccuBond 59992 Useable Case Capaci: 72.511 grain H2O = 4.708 cm³ Cartridge O.A.L. L6: 2.830 inch = 71.88 mm Barrel Length : 24.0 inch = 609.6 mm Powder : Alliant Reloder-26 ? Predicted data by increasing and decreasing the given charge, incremented in steps of 0.435% of nominal charge. CAUTION: Figures exceed maximum and minimum recommended loads ! Step Fill. Charge Vel.
