Some Range Time and Poor Man's Ballistics Testing

Yesterday I finally got out to do some much needed shooting. I had a little fun, but also made sure to get some meaningful practice in. Among the meaningful practice was some weak-hand shooting, point-shooting, GOTX, shooting on the move, multiple targets, and working on my draw. A great resource I've found for mindset and training ideas is warriortalknews. It was a good time, and I feel like I have a better readiness for what could happen in a real situation as a result. Now, if only I had the money to feed it and get more prepared. In all, I touched off 180 rounds of .22LR, 20 rounds of .40S&W, and one 12 gauge. The last one was just for fun, as I'll show you here.

What I did for fun was the ballistics testing. :) The testing target, an ~10" pumpkin:

From 25 yards, a .22LR entrance hole:

The exit hole:

10 yards, .40 FMJ 180gr entrance:

And the exit:

And 10 yards, 12ga 2 3/4" cut shell 7 1/2 shot entrance:

And exit:

 Notice the many bb marks on the entrance side. Talk about tearing up the inside of something real bad. Oh, and it did knock the pumpkin off the bucket, but I put it back to get better pics. Now, for those who don't know what a "cut" shell is, it is when you take a knife and cut through the shell, but not the wad, at the compression area of the wad, leaving just enough of the hull to hold it together to chamber it, but not so much as to keep it from breaking off when you fire it. You have pretty much just turned your shotshell into a specialty slug. I was fortunate enough to be able to recover everything after firing (except the bb's), so you can see the results.
 Left to right - the wad, what was left in the chamber after firing, and the part that left the barrel. What is flared out on the latter is what used to be the crimp on the shell. Yes, it did actually fold over on itself all the way around, like turning a sock inside-out. Pretty cool, huh?

Thus concluded my fun day in the back yard. It was followed by electrical wiring and cleaning, so it was the highlight of my day, even though I do like electrical work.

I hope the showing of this mayhem brightened someone's day.

Act Free.

It brightened my day. Thank you. Are you into crossbows too? I’d really be happy to see what kind of damage it can do. I am still shopping around for a Hunting Crossbows.

I'm glad to have helped someone's day brighten.
I do have two crossbows, one an old wood frame and another which is new and I need to repair, but I don't shoot them as much, though I should since the ammo is re-usable. I don't foresee being able to do testing on that in the near future, and from what I remember from my teen years, the results are not nearly as fun. Crossbows do not fire with enough velocity to create the "shock wave", or if in flesh, the temporary wound channel that yields such impressive results. The difference with a bow seems to be that the arrow/bolt and the head is what does the most damage, as opposed to a firearm where the effects of the velocity can do the most damage.
