For many years i've used the powders made by APP and the old company, Clean Shot. For best performance all those APP granular powders require a tight fitting ball/sabot seated hard on the powder.


The APP made powders are not all the same. They all contain potassium perchlorate and other ingredients; in varying quantities. Want more power from the powder, simply increase the quantity of potassium perchlorate.


i have not used JSG "Super Powder". It may be a re-name of JSG.


Few years ago a ballistician and myself did some testing of the APP powders. At that time we discovered that proper seating of the sabot/bullet on the powder is critical.


1. One hundred grains of plain old APP powder gave a muzzle velocity of around 1,500 fps when used with the .430 240 grain XTP bullet and the Traditions short black sabot.


2. One hundred grains of JSG powder gave a muzzle velocity of about 1,600 fps when used with the bullet and sabot listed above.


3. Goex 2F Pinnacle (made by APP) gave a velocity of around 1,700 fps when used with the same bullet and sabot.


4. Goex 3F Pinnacle gave a velocity of about 1,800 fps when used with the same bullet and sabot.

5. Black MZ gives a velocity of around 1,800 fps when used with the .430 240 grain XTP bullet and the Traditions short black sabot.


APP shot themselves in the foot when they stopped recommending seating the sabot hard on the powder.
