405 gr LC loads fo H&R Buffalo Classic

[JasonYuke]

I just bought a H&R 45/70 Buffalo Classic and am looking for some powders to try with 405 lead cast bullets.
I am new to lead casts and the manuals I have are showing powders that I do not have but am willing to buy what works.
I do have H-4895,4831, BLc2, 322 some of what may work.
Any Ideas what to start at or what preasures i should keep to I am assuming to load to modern standards.

Thank you
Jay
