Muley,
I'll try but forum members know my photo skills would have to improve considerably to reach the awful level.

I'm actually looking at a round from a box Winchester .38S&W as I write this. There is a definite ridge or ring around the bullet just ahead of the case mouth. It sure looks like the crimp is under this feature. Perhaps "heeled" isn't the correct term but isn't this what .22s look like?
