I know that many people use water, clay, wet newspaper and ballistic gel to test pellet expansion.
I was wondering though, if anyone has thought about using foam blocks (like couch cushion material) soaked with water as a test medium? It would have more resistance than plain water, and less than clay - I don't know how it would compare to ballistic gel though. It seems as though it would be similar to a small game animal in that the foam would have some elasticity to it (like skin and organs) and be a fairly decent media to try.
There is an upholstery shop close to my house that I could probably get some medium density foam blocks from them cheap (or even free if they are scrap pieces) soak them in a bucket of water with some old t-shirts at the bottom to catch any pass-through pellets. I figure 4" to 6" squares of foam could at least take a few hits each.
When I get my rifle and the pellets I want to test, I was planning on using clay and small thin-walled water bottles (about the size of a squirrel's torso) to test the pellets and I think the foam would be an interesting addition.
Thoughts?
