The factory ammo is 1050fps. It is subsonic and very stable in flight. Because the bullet is so big and going so slow it tends to hold velocity very well down range. It only sheds 100fps over the first 150yds. What the Paradox bullet lacks in velocity it more than makes up for with momentum. Remember, a slow moving wrecking ball will smash through the biggest and toughest building. Likewise, the heavy, slow moving, Paradox bullet delivers a smashing blow downrange.

tinker - With my limited equipment casting and loading for the Paradox is a real chore. I am glad to shoot the factory ammo. I don't shoot black powder in my gun but I'm sure once the bullet got moving at equal velocity the downrange ballistics would be the same. My interest was in figuring out what was going on between the barrel and the target. I had never seen the trajectory worked out before. I've already seen what these guns can do on game.

Some of these guns were made with three leaves and some with two but I don't think a single leaf would be much, if any, handicap within 125yds.
