I live in the peoples republic of california where ALL hunting with lead projectiles will be illegal as of next july 1. does anybody have an accurate load using copper bullets for a .44 magnum revolver?

Take a look at the Barnes bullets for rifle and revolvers.

Not cheep but they work very well and there are also loads made
by them for hunting needs, if you want to sample what you might be getting.
Barnes suggest Ramshot Enforcer and Accurate No. 9 in the 44 magnum loads
and will give you data if called, if you can't find load data.

The all copper bullets are a lot longer than the lead bullets......
so you need to take that into your types of powder if wanting major fps.

Ps I hunted that area for the small black tail's in the very bushy hillsides around the
family deer camp, not far from town.

Good luck getting a tag and filling it.
