Nice photo.....please tell us the rest of the story.

Here is the link to 24hr Test tube

Little off topic but I've always wondered what happens to the polymer tip on those bullets as shown in the above picture, can't imagine that they would vaporize/disintegrate or do they just harmlessly sail off into a steak somewhere?
Actually I'd really like to get my hands on some of that testing media, would be ultra fun to play with and I may just be able to answer that very question.

"Yes, in some ways. With regard to penetration you can multiply the penetration depth in the Bullet Test Tube by 1.34 to make a relatively accurate prediction of how the bullet would have penetrated inside ordnance gelatin. However, ordnance gelatin does not offer a reliable means for measuring the wound cavity bullets create. And, ordnance gelatin offers a great visual exaggeration of the affects of what has been called the “temporary stretch cavityâ€.

With the Bullet Test Tube you can physically measure the volume of the “wound cavity†which is the actual material physically displaced by the penetration and expansion of the bullet thru its entire depth of travel." From the "FAQ" section of their web site.


An army surgeon by the name of Fackler published a paper in the late 80's on would channel effects; his basic conclusion was that the temporary would cavity was usually not a good indicator of wounding capacity. He notes that on "elastic" tissues, such as the lungs, intestines, etc., the temp wound cavity simply "rebounds" back into place.

More important, he argues, it the permenant wound channel, the consequence of penetration.

When a bullet encounters "non-elastic" tissue, however (liver, bone, etc), the "temporary" cavity is much more "permenant"!

Anyway, it's interesting reading...I can supply the link if anyone wishes.

Take care,

Hey Don, Are you going to try this thing out?
