You didn't specify bullet weight, and I surmised that you were speaking of the 175 grain LRX.

Cartridge : .300 WSM (CIP)
Bullet : .308, 175, Barnes 'LRX'BT 308807
Useable Case Capaci: 68.272 grain H2O = 4.433 cm³
Cartridge O.A.L. L6: 2.860 inch = 72.64 mm
Barrel Length : 22.0 inch = 558.8 mm
Powder : IMR 4350

Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

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 !

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