[QUOTE=sabotloader;4300298]That is kinda odd - since BH is a smokeless progressive burning powder the should have been a little less recoil in the same charge. BH does not produce the same peak pressure as a T7 load.
That really depends on the weight of the projectile. The heavier the projectile the more efficient BH becomes.
Up to the 250-260 grain projectile the powder shoots nearly the same velocity as does T7 and Swiss BP
This spread sheet shows some of the numbers. The powder loads were all by volume.
The BP seems to have more of a shove while BH is more like the punch of smokeless powder. Velocity may be the same but recoil is different.
