MGM’s uniquely designed Propeller Plate Rack is a spinning plate rack with Eight 8 inch 3/8″ HEXALLOY 550 HEXPlates. The targets drop off when hit, just like our normal Whirly-Gig® products. However, as the weight distribution varies, the main beam starts to spin. Once the angle reaches a certain amount a weight drops off the end of the beam, changing the weight distribution and possibly the speed and direction of spin. There is a weight on each end of the beam, potentially giving the shooter two major changes of speed and/or spin.
Here is a link to a .22 version we did, but the concept is the same.
This video will give you a good idea how this devious device works…
