[QUOTE="MarkA, post: 1226366, member: 5220"] Note loaded longer than Saami Max OAL to touch lands and with 140 amax but should give you idea of speeds and upper charges. Forgot to include RL26 as it would viable candidate also. Have found RL26 to be a bit faster burn rate than RL25 data in the magnums just cleaner and better temp stability but not as stable as H1000, so yes H1000 is hard to beat. Cartridge : .264 Win. Mag. Bullet : .264, 140, Hornady A-MAX 26332 Useable Case Capaci: 77.269 grain H2O = 5.017 cm³ Cartridge O.A.L. L6: 3.500 inch = 88.90 mm Barrel Length : 26.0 inch = 660.4 mm Predicted Data for Indicated Charges of the Following Powders. Matching Maximum Pressure: 62000 psi, or 427 MPa or a maximum loading ratio or filling of 105 % These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window. C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand that all of the listed powders can be unsuitable for the given combination of cartridge, bullet and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations. USE ONLY FOR COMPARISON ! Powder type Filling/Loading Ratio Charge Charge Vel.
