I got this from another forum:

For example, the regular plated bullets from Xtreme, Berry's, etc have copper plating about .0035" thick, while their heavy plate bullet will be plated to a thickness of .007" to .008". In comparison, traditional drawn jacket bullets vary between about .013" and .026" in the side walls and are usually a bit thicker in the base, due to the jackets being drawn.

I was able to use someone's chrono at the range today.
Turns out that 6 grains of unique gives me 980-1000 fps.
