bobnob":154xlev0 said:You have made a good start to our journey of exploring these new bullets! I am so keen to try the .277 version in my 270 Win.
Same here Bob. Really looking forward to that 150.. Should be a heater in the 270's!
That's a great idea Brian, be cool to see what the 308 does with them..

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 62000 psi, or 427 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 !
103 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
