270 WSM Quickload Request

[Gun nut]

Would like to have some Quickload info run on the 270 WSM, if possible.
Will be using the following:
Winchester brass ( the silver colored stuff )
Reloader 22, H4831C, (also open to suggestions)
Winchester large rifle magnum primers
150 gr. Hornady SST (#27402)
COAL 2.785"
Kimber 24" barrel
Comments, suggestions are welcomed. I haven't reloaded for the 270 WSM before.
Thanks,
Duane

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 !

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