Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63250 psi, or 436 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 !
12 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

I am happy using 74.4 grains of RL-22 , Norma brass and 180 AccuBond. Shoots .2 to .3 MOA @ 300 yards at 3,165 fps with 26 inch barrel. Chrono showed less than 10 ES. Do not use without working up.

There's a pretty good spectrum of powders that will work. Nothing wrong with that.

Oh, yeah, that'll do! Excellent load and some fine riflery.
