45-60 Winchester, 300 gr LRNFP, and IMR SR4759

[hockeynick39]

Does anyone have any data for this combination (in the subject title). Already have a load with IMR Trail boss. just trying to see about the last bit of SR4759 I have. Thanks in advance!

Lyman's 49th reloading manual actually has a comprehensive article by Brian Pearce that included the 45-60 WCF. This is the only reloading data for the 4 factory chamberings in the 1876 Winchesters, that I am aware of. Unfortunately he did not include 4759. The four rifles he tested were Chaparral's, modern day reproductions.

I would find a modern day Lyman Cast Bullet Manual. Look up 45-70 Trapddor Loadings and reduce the starting load by 15%. Lyman's 49th Manual includes 4759 in it's 45-70 Trapdoor load data.

IMR 4198 or Trail Boss would be your best powders. Actually, Black Powder is your best choice.
