Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 59250 psi, or 408 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 !
2 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Thank you sir! I will try a couple of those, I will stop at 2900+ when accuracy shows up. I don't need to strain anything with this load, and I didn't want to sling my 120 NBTs out on a regular basis. God bless Brother!
