I love 2400 powder for reduced loads... I bought 24lbs of it so I wont run out!!Sounds Like you need those Bullets sized to .459 Thats what I cast/size for mine and for my Mouse fart loads I shove 26 grains of 2400 under that bullet I know MOST of youboys must think I,m nuts But if ya have a Lyman 43rd or 46th They have 2400 Data in there and back in the day they were using Herc powder and supposadly the IMR is supposed to be reduced by 1 grain at max loads so reading the data on the 2400 Your right in the ballpark with 26 grains Nice little LOW recoil load and with Recluse,s -45/45/10 lube I don,t get leading with even PB bullets and MAX Loads
Enjoy It,s all Good
c.t. smith,Cant tell you a temp but I cast hot and with some tin in the mix to cast big. For the OP if you can find .460 bullets that's what id buy, let your barrel size them to the correct dia
I have casted bullets a bit but thats all been for my .45 acp so far. And at the velocity those go down range they are for more accurate then anything you buy. Now as for the .45-70 I have a Remlin and have been shooting the .457 diamter lead bullets. It may not be one hole accaurcy but having the largest rifle range out here of 100 yards I find it to be suffuicent for my needs for right now. But when I start casting my own I have my own lee molds 405 grain .457 molds they cast big for me for my .45 so I magine they will probaly be around .459 anyways. Just my thoughts. My Lee molds have always made alrger diameter bullets then what is stamped on them. Just my .02. By the way I shoot on Pyrdoex in my .45-70 as smokeless anything is hard to find. Less than 40 dollars a pound locally. So I use the bp subsitue since it runs about 13-17 bucks a pound.
