no problem. 4.5-4.7 grs of Unique. With care,using the Lee many-grooved lrn,Lee liquid lube, and AA powder,you can get it up to 1100 fps,too. so you can do most of your practicing with 9mm ball, use the heavy bullet 9mm loads, and have SAME recoil as .40 Short and weak, without the pointless extra expense of .40 gun, components, etc.
