As Fingers said, 777 is a good bit hotter than true black or any of the substitutes.
As an example, my standard load of 80gr of 2fg 777 with a 300gr sabot in my rifle is the equivilent of 90gr of Pyro RS or 105gr of 2fg American Pioneer (Shockeys, CleanShot, or whatever else it's been called). This produces 1500fps at the muzzle with a barrel of 22" length.

For my 1858Rem, I've dropped from a full 30gr load of 3fg black to 25gr of 3fg 777. What you have to watch out for is loading consistency, 777 seems to pack really well so can be over-compressed while loading...................this hasn't been any issue with my rifle shooting, but I've definitely noticed it with the pistol.
