[QUOTE="beretzs, post: 848188, member: 15154"] I am working with the 150 Swift right now as well, only in a 7mm Rem Mag. I started them .050" off the rifling, on a hunch that is where they will like to be anyhow. Either way, let me know how you make out with them. Here is some QL information for you. Cartridge : .280 Ack Imp Bullet : .284, 150, Swift Scirocco Useable Case Capaci: 64.807 grain H2O = 4.208 cm³ Cartridge O.A.L. L6: 3.330 inch = 84.58 mm Barrel Length : 26.0 inch = 660.4 mm Predicted Data for Indicated Charges of the Following Powders. Matching Maximum Pressure: 63000 psi, or 434 MPa or a maximum loading ratio or filling of 110 % 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 ! 9 loads produced a Loading Ratio below user-defined minimum of 90%.
