Couple of high school text books  I was at the range today and noticed someone had left about four text books over on one of the benches. They had already been shot apparently, so I decided to see just what a 440 grain at 1350 fps would do. I grabbed the two thinnest books and figured it would sail right through those, but it would be a good initial test. Well, as you can see, they were more than sufficient to stop that round. I stacked both books tightly against each other and shot them at a range of 25 yards. Here's the book that was in front, with an arrow showing the entrance hole  Easily punched through this one  This was the second book. You can see from the entrance hole that the bullet had already mushroomed, or was starting to break up  And here's the page where it stopped. Specifically, the bullet fragments were clustered around this lady's hoo-ha region (no, I'm not making this up). Let the wisecracks begin...  The remains of the slug next to a loaded round with the same bullet  Approximate total thickness of the books  Approximate depth penetrated  So in conclusion, the 500 JRH is more than capable of handling 2200 lb. bison, grizzlies, cape buffalo, and other large fearsome creatures. However, if you are planning on hunting the common high school Human Anatomy & Physiology text book.....you might want to consider something with more power..... ;D |

Hmmm...That is interesting...Nice to know the school kids are safe with a full backpack
Nice that you also left that open to the anatomy shot, that was most helpful. I was wondering where some of that stuff was located

You need a bigger gun! Good thing you have a 500L coming.  |

By the way, that's a 440 grain Lee #90991, with gas check (which stayed on, surprisingly). Don't have any idea how hard they are, though, or the alloy.

A dry compressed book is a formidable medium......

If I had to guess Id say the bullet is on the hard side based on everything I've read and heard about different alloys.
I'm a little suprised it didn't penetrate further, 440gr is a lot of mass.

I would have liked to shoot those textbooks while I was in college. They were boring reading.

Very interesting to say the least--and more surprising. I haven't shot books, but have shot 475L and 500L through and into landscaping timbers, standing birch and spruce trees about 8-10" I'm diameter (ones were about to cut down anyway) and end-to-end log rounds. Went through the landscaping timbers and standing trees. Shooting into cured birch rounds lengthwise, got about 11-12" of penetration in one of my 475L loaded with 420lfn's.
Would have figured those books would have simple ended up with .510" holes on either side. Now I gotta wait for the library sale.

Dry paper tightly stacked is very difficult to penetrate as the range report clearly demonstrates.

Yep, kinda wish I'd gotten a chance to shoot the other two books with a different bullet (a RNFP, 420 gr, from Hunters Supply), and also with my 454 Casull. Range was kinda crowded so it wasn't really easy to shoot the book then go look at the results without waiting 30 minutes before the range went cold.

Goes to show you even a big bore 500 JRH is no match for a woman's hoo-ha!

You could have shot some sociology and political science books.......

Well gosh, what are people doing paying big money for bullet resistant vests then? All they should have to do is buy a roll of duct tape, join together some old college texts, and be on their way stopping big caliber bullets. I have a suspicion that if you shoot these books with a 44 Magnum slug, that it will go through and then whistle across the landscape behind it.

This is terribly juvenile but the name "HOLE'S" is just entirely inappropriate for an A&P textbook!!

I have a suspicion that if you shoot these books with a 44 Magnum slug, that it will go through and then whistle across the landscape behind it. There was an episode of Mythbusters where they tested dry phone books as make shift bullet proofing. The results were surprising. It stopped all handgun rounds, and many rifle rounds. I'll have to watch that episode again to see what finally made it through (I know 338 Lapua did). I would also be interested to see if a more sectionally dense bullet like a 330+ grain 44 mag would have done better, or a bullet with different hardness/alloy, or nose profile (these are more of a WFN, maybe LFN would have been better), or running the bullet slower (like 900 to 1000 fps), or using a thick jacketed slug like the Hornady XTP Mag. Clearly, more testing is in order! |
