Stat - Here is the data right out of my old Lyman Reloading Manual for these bullets with your chosen powder of 3031. These loads are for modern 45/70s ONLY.
300 gr cast bullet - 3031 - Starting load = 44 grs - Velocity = 1517 fps
Maximum load/3031- 50 grs - Velocity 1782
400 gr cast bullet - 3031 - Starting load = 42 grs - Velocity = 1492 fps
Maximum load/3031 - 48 grs - Velocity = 1745 fps
Hope these help you.
Pavo,
Yes that did really help me out a lot. The 300gr load I can work with right away. However, I have a 425gr bullet not a 400gr. Does the book list a 425 gr bullet? If not how should I change the load to load for a 425gr bullet?
Any body with info on changing a load for a heavier bullet without the load data please respond. I do not want to end up in a dangerous situation.
Thanks
Tom
