I am running them at around 750 FPS in the .44 Spl. Pretty light load.
Titegroup is a hot burning powder (High Nitro content) It will smoke worse than a single base or low Nitro content powder like American Select. (>10%, but <15%)
700X is double base, and smokes a good bit with lead bullets, but can be very accurate. I do not know the Nitro content in 700X.
The bullet shoots quite well.
