What Kind of Shooting?

Shepherd K and Robert Slaughter ask the question

What ‘simulation’, if any, is being demonstrated?

It’s mimicking 25 yard shots at squirrels. Specifically, squirrel heads. Like a walk in the woods with a .22, taking squirrels as they appear. Head shots avoid damage to the meat and to make them drop right there.

So that decides the sling question. A hasty sling is okay. As demonstrated here.

If this gets good participation, we’ll try some other targets and situations in the future.

In theory there is no difference between theory and practice. In practice there is.
