For a little test. I'll let you know what it's about if you've got some 1" thick HDPE you can sell me at a reasonable price. 8x8x1 would probably suit me for now, I'd definitely buy some more depending on how the experiments go.
It'd be nice to get some before this weekend, as I'm planning on hitting the range then.
