Thanx, I had a few friends in the 508th Almost wish I were back in, I served back in 99' - 03'.
I just got home from shooting today, and spent time shooting at my homeade "ballistic penetration box"... I've been using it for a couple years now, to test centerfire rifle rounds' penetration and tissue damage capabilities.
What I do is take a box, preferably 30" long, 16" wide, and 16" high. It doesn't matter how wide/high it is, but the more, the easier it is to see/shoot, as this is the target face. You do need at least 24" or so worth of length, to stop the bullet. Then, I take old phone books, Sears catalogs, tightly stacked and tied newspapers, anything I can find that's thick, tough, and tight, and fill the inside of the box up with them, standing them up in a row, all the way down the length of the box's interior. Now, wet the books/paper until it's almost soaking. You can even add some other things to simulate things like bone. Today I had a 1/2" square of plywood every 4-6" down (I needed it to help stop the round, 7mm Rem Mag's shooting long, high BC bullets are HARD to stop!)... and now, put a target on it, and shoot it! Depending on the size of the box, you can usually get 2 or 3 shots into it before it's too weak to stop the round. Today, my box was 28" long, and at 100yds, could not stop a 160gr. Barnes TSX from a 7mm Mag (my LR deer rifle), but when I shot again from 225 yds, the bullet stopped about 1" from the end of the box, and told me a LOT about how that round performed. It expanded perfectly, into a petaled mushroom shape, and appeared to penetrate about 7" before expanding. After the initial 7" of hole, it started opening up, shredding the paper books - opening up the hole, or "wound cavity" up to almost 6.5", and stayed that size for almost 16"! Inside this "cavity", there was just tiny, tiny little bits of wet, shredded paper, and a few tiny bits of copper. Last time I shot this rifle into my "box", it was using a Nosler ballistic Tip, and I never even found a piece of the bullet bigger than .5" LOL. Anyways, my point is, my method showed me that this 160gr. TSX is a performer, and a wicked deep penetrator, and is probably too "strong" of a round for deer, but at 500yds and under, should still expand. Would make a wicked elk, moose, or big bear bullet.
