Has/does anyone use bundled wet cardboard for testing? When I was working, I had access to unlimited amounts of waste newsprint that I found worked well. Now, I have access to a supply of boxes that could be handled similarly but am concerned the wet cardboard will simply break up the bullets(over expand) rather than mush like wet newsprint does.
We've been using water filled milk jugs but even though spectacular on impact, I don't feel they give a realistic representation of bullet performance-there's no permanent cavity.
