I have a Lyman 48th edition reloading manual that has both jacketed and cast load for a substantial number of calibers. I've never used the cast loads to date, but after getting the 45-70, it really seems appropriate to start.
I find the Lee manual very helpful but one of my favorite sources is the online Hodgdon load data site. My only caution would be that the loads in many manuals are quite a bit milder than those listed at
http://data.hodgdon.com/main_menu.asp If you use the Hodgdon data be sure you start at the start load and work your way up... preferably with the help of a chronometer. And be very sure about which brass you are using as there is quite a volume difference between Remington and Winchester for example. I won't go into the details here - you can find several posts in the reloading section on this forum - but many of the experts say you can get into dangerous pressures if you build hot loads with the wrong brass.
I am waiting to get my hands on a copy of the new, 8th Edition, of the Hornady reloading handbook. My buddy has one and it is very good... however it is quite conservative compared to the Hodgdon site. I have found that reloading is more of an art than rocket science, you have to find the best sources you can for information... and then use your own best judgment. That said I enjoy reloading almost as much as shooting...it has opened up a whole new dimension to the sport.
