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 !
31 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

RL19 has always provided top accuracy in my rifles, and excellent velocities as well.

Magpro has been a proven winner for me in several rifles shooting the 140gr NAB. I like RL17 and RL19 with the 130's, but like others have mentioned, several powders work well in the WSM's.
