Here is a test involving the hunting & self defensive bullet made by Speer and produced from Georgia Arms. This Speer Unicore Bonded Hollow Point Bullet in the 9mm/124gr./+P caliber was made by Georgia Arms was tested against 4 layers of denim & water jugs with a G-Lock 17 fired from a distance of 8 feet.
After the test, the expanded bullet was discovered in the 4th jug (with a added note of almost going into the 5th jug).
From looking at the test results, the bullet opened after passing through the 2nd jug's back section. No lead or pedals were found in any jugs. With over 24" Plus penetration & complete opening of it's hollow point, a perfect ammo test was concluded.
