Has anyone tried loading up the 45-70 with a 405gr cast bullet?I only see medium velocity loads listed in the 1500fps range,but I see that some loaded ammo is avaiable out there with a 405 gr.cast bullet @1800fps+

Pressure for the gun

Lyman has data listed for several differing strength actions. This data is also dependent on the case used as there might be old balloon style heads out there.

In the strongest action, the Ruger #1 and #3, velocities range to 2400 ft/second with this bullet. That will bring donw ANY North American game, Polar and Grizzley included.

You will find what you need here. Beware though, these loads hurt!

jnixp, if you're interested in cast,use a good bullet. You can find a lot of loads and FAQ's here.

Thanks for the info gentelman.I have one question:
How do you approach loading a round with a cast bullet if the data you find has data for the same weight bullet,(400),but in a JACKETED bullet?I assume there must be some difference in pressures generated between bullets weighing the same,but lets say one is jacketed,one is hard cast,and one is hard cast with a gas check.I'm trying to work up a 405gr premium cast load for my Marlin guide gun for Elk this year.

Jnixp. You can use jacketed bullet data for cast bullets, but not the reverse. Usually, the cast bullet will give somewhat higher velocity than the jacketed bullet, usuing the same powder charge for both.
