Looking for QL data for the 45-70 using the 350 gr. Barnes TSX FB loaded to 2.800" and a MAP of 31000psi
IMR 3031 would be my first choice, but have a good selection of powder to choose from.

Much appreciated.

or a maximum loading ratio or filling of 112 %
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.
