[QUOTE="jimbires, post: 1326472, member: 11011"] here is a chart from Q-load that is set up for your combo . it steps up by 2% powder charges . it'll give you an idea where your at . it looks like 3080 FPS is max velocity for this combo , at 61143 PSI . Cartridge : 7 mm Rem. Mag.(SAAMI) Bullet : .284, 162, Hornady ELD-M 28403 G7 Useable Case Capaci: 78.557 grain H2O = 5.101 cm³ Cartridge O.A.L. L6: 3.465 inch = 88.01 mm Barrel Length : 26.0 inch = 660.4 mm Powder : Alliant Reloder-26 ?, Temperature: 72 °F Predicted data by increasing and decreasing the given charge, incremented in steps of 2.0% of nominal charge.
