Ballistic test: .44 mag from a carbine and 10mm 135 gr cast bullet

.44 mag Winchester 240 gr JSP video link


.44 mag Winchester 240 gr JSP fired from Marlin 1894 carbine into calibrated gelatin and calibrated tactical rain water.

BB: 594.1 fps, 3.4"

Gelatin test data:

Impact velocity: 1,848 fps
Penetration: 21.1"
Retained weight: 231.4 gr
Max expansion: 0.711"
Min expansion: 0.732"

Sorry about the cross section of the wound channel. This load really crushed the block and caused a substantial amount of disruption, especially in the first 10" or so. When I cut into the block for the cross section photo it practically fell apart. The photo really doesn't do justice to the damage that was done.




10mm 135 gr Mihec video link


10mm 135 gr Mihec 10:1 lead/tin alloy over 12.5 gr SR 4756 fired from 4.25" barrel S&W 1076 through four layers of denim into calibrated gelatin.

BB: 594.1 fps, 3.4"

Gelatin results:

Impact velocity: 1,548 fps
Penetration: 7.1"
Retained weight: 73.0 gr
Min Expansion: 0.651"
Max expansion: 0.708"

We fired a few rounds over a chronograph with the same powder and alloy but different charge weights and these are the velocities we got:

11.0 gr 1,512 fps
11,5 gr 1,484 fps
12.0 gr 1,568 fps
12.5 gr 1,610 fps

Nothing like a 10mm to get the day started and blood pumping.
