Was just experimenting today (just cause, ya know?) With 357 mag shot shells and saw a 00 buckshot shell on my bench and thought, why not? Found i could fit 2 balls in a case and they weigh 111 grains or something. So i load em upwith card on each side and just play around. Then get the bright idea to put one of the lee 105 grain swc on top of one ball. Was kinda cool, only shot one of these cause it was getting dark spread was about 2 or 3 inches at about 20 to 25 yards. Was just kinda neat to be loading aimlessly.
Have no clue what this could be used for, but it was fun!
