I'd love to video this thing, but it doesn't belong to me anymore.. I tested one out a few years back and was trying for accuracy 'lobs' at my aunt's lake. Needless to say, 450g of ffg black powder will send a golf ball about a half mile or so. You can see it fly and it just keeps on going and going and going until it's out of sight. Also figured out not to patch the ball or it puts a tremendous amount of spin on it. You can get a boomerang of a slice or so much topspin that it'll crank itself into the ground just ahead of the mortar. 100g of ffg will make a good thump and you can lob balls about 300yds or so. If I can talk my friend's boss into it, I will see if he will video it. He has about 75 acres, almost enough room to shoot it safely. BTW Trek, I haven't talked to the Boss about another yet, but I bet I already know the answer!
