Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 64000 psi, or 441 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 !
50 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Their bullets are somewhat like Barnes, they have groves cut to reduce drag. They still engage the rifling more than the seal tite band. It's used more as a reference for seating depth. All of their BC's they have listed they have tested with drops and some of them Bryan Litz tested for them.
