New member here... and am a long time reloader... However, I've never loaded ANY cast bullets for my double rifles and want to start with my .375... There seems to be a lot of opinions, myths and even some rumors regarding cast bullets, hardness, velocitie, etc...

Has anyone loaded cast bullets for a .375 (or a big-bore in general).

What velocity ranges do you reccomend?
How do you distinguish between "harnesses" (without consulting labs and MOHS scales)
Are there any pressure differences between cast and jacketed bullets?

I don't want to "pour my own" - but am looking for a starting point without blowing something up!

your insight and experience would be greatly appreciated.
