I am revisiting the multiple ammo issue.
Not so long ago, I designed the shotgun pouch made from Kydex. A good thing, really - but I have moved on to far heavier ammo in the meantime.
So now I will be shooting 8mm steelballs - 30 of them at a time. That is right, THIRTY. Makes a total of 60 gramms, just under the weight of a 25 mm steel ball.
I am testing Bill Herriman's report that you can use tissue as bags. He says the tissue opens and drops to the floor.
I think he is correct, but the trick is to find the right material for the bags. A single sheet of kitchen tissue works in general, but some of the balls come back and hit your shooting hand. Ouch!
I am using my octa-slingshot for the tests, as it protects my hand 100%. I even added a leather "skirt" to protect the back of my hand.
The wood already got a few hits... my hand is fine.
Will test paper, aluminum foil and maybe toilet paper later on. There must be one that opens, but late enough so no balls come back to the shooter.
