It would be great if you could slow that down to super slow motion.
1,200 FPS (frames per second) is as fast as our company's camera will do, Max. I have compared this mod. clip with an unaltered one and the speed is the same. The lanyard whip is just as DD says and has nothing to do with wind.
Parrott-Cannon, It's dangerous to assume anything, but I will assume you want the bore diameter of 11" and NOT the O.D. of 25". That would be much appreciated if you could calculate the velocity,
then we could get a muzzle energy figure which, with a 137 pound shell, is going to be substantial.
Dan, Double D is pretty sharp today, and I unintentionally mislead him originally, as I called that smaller lagging projectile a piece of water jug plastic when he asked that same question after the shoot. Several did shred their plastic skins, but that shot was not one of those and the piece of material coming out after the jug left us behind, was a wadded up ball of aluminum foil. We used 6 layers of heavy duty foil and with a hemispherical chamber, 4" X 8" long, quite a bit of foil is used for each shot.
Mike and I looked at that clip quite a few times and we guess that mass of concrete is traveling at 150 feet per second. Parrott-Cannon will tell us if we are close or not.
Thanks DD, for the mod. We got tired of waiting too.
Tracy and Mike
