If you look at the fine print on that load, you will see that they tell you to use 6, yes, six, .135 card wads to fill the shell. In addition, it is an unbalanced load if you reduce the powder. Unique is not the powder to use in a 1 1/4 ounce ten gauge load if you want sensible velocities. You don't reduce the powder charge in a 7500 psi load to reduce velocity. You go to a faster powder in order to reduce velocity and at the same time keep pressures up. If you take this load and reduce the powder charge, the pressure will go through the floor and you will get squibs and bloopers, especially in cold weather. Read the "burn rate chart" to decide what powder you should or should not use. If you need to reduce the velocity in this 1265 fps Unique load, you should not reduce the powder charge, you should go to a faster powder, like Green Dot if you choose to use an Alliant product.
