Useable Case Capaci: 89.416 grain H2O = 5.806 cm³
Cartridge O.A.L. L6: 3.560 inch = 90.42 mm
Barrel Length : 26.0 inch = 660.4 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 64250 psi, or 442 MPa
or a maximum loading ratio or filling of 112 %
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 !
66 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
