Unscientific Ballistics Testing

I picked up defensive rounds from 9 Forward at the Cup last week. I rode up to Oxford with a practice partner Saturday morning (June 27th) and one of my goals was to try the defensive rounds in the two guns I rely on for defense.

The “Library” was still in place, although a bit soggy, and I used one of the books to test penetration and expansion of the defensive rounds. Note the book on the top right shelf. It was wedged in tight and just the right height. It was also seriously thick, partly due to the rain soaked pages.

I put 3 round in on the right side of the front cover. My practice partner suggested I also put in 3 rounds from my regular ammunition. I shot a row of 3 on the left side of the front cover.

I took the book off the shelf and started turning pages to see the impact patterns and find the lead and casings.

  • The defensive rounds penetrated 1110 pages. They torn much larger, irregular holes.
  • The practice round penetrated 1600 pages. The holes remained round and uniform.

If you are local and want a first hand look at the book, let me know and I’ll bring it to a match. I’ll hold onto it for a few weeks, then it will go into the recycling bin. 

Here’s exactly what I was using:

I really liked the lighter recoil of the defensive rounds but unfortunately they stove piped in both guns several times. That’s why you try ammunition in the gun you plan to use it with: to verify they work well together. I’ll go back and buy regular defensive rounds to test as the “Lite” version failed in my guns. Bummer but better to know now.

This was still a very interesting experiment for me. I know what the outcome is supposed to be but touching the book, turning the pages and digging out the lead and casings felt like an adventure! Here’s what I found:
