Why can't they shrink a wad?

I'm looking at my target loads and it seems like most of the shotshell is air from the wad.

Seems like most of that space could be used for extra gunpowder/shot.
 
Look at some fired wads. They compress, and this is deliberate. It cushions the shot and helps keep it round. The center section is made to fill up the needed length inside the hull when made, and then compress at launch. Rounder pellets stay in the pattern and keep the density up where it belongs.

FYI, forces at launch are on the order of 60 G.

This is one of the reasons that modern ammo is so much better than the old stuff. A modern 1 oz load will put more pellets of any given size in the center of the pattern than an old fashioned 1 1/8 oz load.

HTH.....
 
Good comments above.

Remember that every type of wad has been designed for maximum performance with the hull type, powder, and shot charge.

The wad is a shot cup, shot buffer, gas seal between the powder and shot, and a gas seal for the shot as it leaves the barrel. It was the plastic wad that made the "forcing cone" less of a necessity.

Once the wad leaves the barrel, the open end slows the wad so it doesn't "push" the shot and deform the pattern. A good wad for clay shooting will only fly about 20 yards before it slows and falls to the ground. Hastings Barrels went as far as straight rifling or grooving their barrels to further slow the wad.
