Perma-Gel Tests |
|

|
Perma-Gel is a new ballistic testing medium producing
results closely resembling the more traditional ballistic or ordance gel
in testing hollowpoint and expanding ammunition.
(Full metal jacket ammo tends to penetrate further in Perma-Gel than in
ballistic gelatin.) It also has the advantage of being
able to be re-melted and recast and without the necessity of
refrigeration required by ballistic gelatin. |

We were interested in testing the claims of two
manufactures of the new frangible ammunition such as the compressed
powder ammo by DRT www.drtammo.com
and the frangible ammo by Extreme Shock produced for use in aircraft to
stop the bad guy without shooting through plane.
www.extremeshockusa.net. The concept of frangible ammunition
is to produce trauma in soft tissue by a large temporary cavity and not
penetrate two sheets of drywall. Results on drywall will follow
later.
We also wanted to test some of the original Winchester "Black Talon" and Winchester's replacement
"Ranger SXT" law enforcement ammo.
All shots were 9mm from a Glock 17 from 6 feet into 18" of Perma-Gel.
Five bullets were tested:
- (A) Winchester's original 147gr.
"Black Talon"
-
Full expansion and just over 18" penetration
- (B) Winchester's Ranger SXT 127gr.
+P+ (Law
Enforcement)
Full expansion (larger surface
area than original "Black Talon" and
15 1/2" penetration
- (C) Dynamic Research Technologies DRT
(compressed metal powder
Passed through the
18" block but didn't show any evidence of expansion
- (D) Extreme Shock AFR (Air
Freedom Round)
Strong fragmentation
and penetration from 3"-9" Company claims that this round
will not penetrate 1" drywall.
(We'll test this in the near future.)
- (E) Extreme Shock EPR (Enhanced
Penetration Round)
Penetrated all 18" of
gel but shed large parts of round
