Basically what I am wondering is can you get the same velocities as a longer barrel out of a shorter barrel by using a faster burning powder? For .308 Win, out of a 24" barrel, a 180 grain bullet will move at 2550 fps. Let say (for the sake of not knowing what actual powder was used) 49 grains of H414 was used to get this velocity. If you were to cut that barrel down to 16" you would get a velocity of 2370 fps with the same 180 grain bullet. If you were to use a faster burning powder like H4895 in the 16" barrel, would you be able to bring the velocity back up to 2550 fps? If so, would this be dangerous, pressure wise?
