Ammo Test - Kahr K-9 Taurus Millenium 9

[dean1818]

As part of my son's science project, we tested penetration and expansion for

Speer Gold Dot 9mm +P 124 Gr
Speer Gold Dot 9mm +P !24 Gr Short Barrel
Ranger HST 147gr
Cor Bon DPX 115g +p

We used the Kahr K-9 and the Taurus

To test the data we recreated a test done by a fine gentleman from Tennessee (you should subscribe to his videos) on youtube, who did an excellent job. (Its an easy search)

What I wanted to do is check the results with a pistol that is less than 4inches long (The Taurus and the Kahr) to see if the lesser barrel would create a change in bullet performance

Here are a few pictures of the setup.

I used milk jugs full of wet newspaper and on the fron of the first jug, used 4 layers of denim

Results Kahr K-9

Expansion Penetration

Speer Gold Dots 124 +P .625 10"

Speer Gold Dots 124 +P Short Barrel .625 11.5"

Ranger HST 147g .625 14"

Corbon DPX 115g +P .688 15"



Results Taurus 9m

Expansion Penetration

Speer Gold Dots 124 +P .565 16"

Speer Gold Dots 124 +P Short Barrel .565 16.5"

Ranger HST 147g .625 14"

Corbon DPX 115g +P .688 16"




Overall, the Corbon has become my choice for CCW for my Kahr after seeing these tests, and the tests done on youtube.

(The Taurus is borrowed)

Something looks strange to me. The Taurus has significantly greater penetration with less expansion than the Kahr using the Speer ammo. Ten inches vrs sixteen inches is quite a large difference.

What is the reason for this great difference I wonder?

Good pics, thanks for posting.

I dont know why there was such a difference.

I actually shot the Kahr twice and got the same results with the Speer

But..... my "labratory" is a creekbed.........so, nothing exact about it

Just thot i'd share

The Kahr has polygonal rifling, wonder if that has any effect.

I wish I would have thought to do something like this back in the day when I had to do science projects. I might not have dreaded them so much.
