Need a load for Hornady 350grfp and H4198 for deer and blackbear, in the Hornady Sixth Edition it shows a start load at 37.1 to a max of 48.4 what would be a good starting point? What would be a estimated FPS one would be looking for? Thanks 
JohnC said:second what Johan22 said work your way up. there are 3 levels of loads for the 45-70 - minimum for the old trapdoors out there (this is what factory is loaded at), medium (for the newer ) marlin 1895s and high for the ruger single shots and Siamese mausers. do an internet search under 45-70 loads especially the powder company sites there is gobs of info out there.
