Which 777 are you comparing Black Mag'3 to? If you are using ffg 777 then the answer is yes; Black Mag'3 in my Omega registered higher velocities with 300gr. bullet/sabot projectiles both being 100gr. volume charge. Black Mag'3 is basically a fffg powder so the energy per volume is somewhat higher than if it was an ffg powder. I am a little surprised at the comment on recoil however; since I experienced higher "felt recoil" with the ffg 777 powder over same volume of Black Mag'3. My feeling was the 777 is a quicker burn powder which give a sharp recoil like a smokeless magnum rifle whereas the Black Mag'3 slightly slower burn feels more like real blackpowder even though the velocity of Black Mag'3 was greater.
