HI DonT,
I guess my bubble must be off a little too because that sounds like a great idea to me.
I make snake loads for my 44 and 357 by putting a small charge of powder in the case, then pushing a gas check down over the powder, then fill the case with shot, then crimp a gas check upside down over the shot.
I have used this load in rifles and revolvers to kill stray cats, woodpeckers that are trying to invade my house, and they even work good on grouse. In Idaho you can shoot them with any type of weapon.
The only caution is to get the right amount of powder in the case. I tested one of my first loads on a sheet of plywood at about 15 feet and got showered with shot when it bounced back at me. I added enough shot to get the shot to stick in the plywood and they work great.
