Has anyone considered or tried adding a (?) rubber (?) compound to the cavity of a HP like a Gold Dot to imitate a Hornady Critical Defense round, that might have less chance for plugging and perhaps improved full expansion? Is such a rubber like compound available?

GE Silicone Seal.
It's available in small tubes at any hardware store, and most grocery stores.

Many years ago, I used to fill cast lead hollow-points with melted candle wax.
And yes, it improves expansion.

The wax is hard when cool, but turns to a melted liquid instantly when the bullet impacts something.

I have never tried it on JHP bullets, but it should work.

silcone works (non-compresible fluid), have tried rtv sealant. Careful to get the air bubbles out, and none beyond the leading edge of hp cavity. its messy. Highly un scientific testing indicates it can lower expansion velocity almost 100 fps in 45 acp, and not "plug up". Have also tried it in 158 grain lead hp in 38 special.

It is a whole other discussion wether or not it is advisable.
