Pretty much a standard looking Barnes bullet! These were fired into a medium called the bullet test tube. A wax medium that comes real close to mammal muscle tissue.
Wound cavity is real hard to see with an all-copper bullet. No lead "wake" to see where it went, or how much disruption it made. Entrance was on the right, it made it all the way though 8" of medium, and was found after penetrating 6 layers of rags in a back-up tube. The petals open just after impact, the max energy dump is right away, if you can see the "bubble" at the beginning of the wound cavity. Then the bullet penetrates as a solid.
This was fired in my 20" bushy AR-15 with a 1-9 twist. Impact was @ 25 yards.
