Here is some pic of my 17 fireball. This is the damage I see 90% of the time. If I take a hard angle shot I am getting the fishing line and needle out. Some was shot with a 25 grain hp Berger and some with a 20 hollow point blackout
This was an entry side
This was another entry side
This was an exit side. I have never had an exit with the bullets listed above
For what it is worth a cat is thin skinned and use a 25g hp Berger with the same results. Also want to mention that 99% of the shots are within 40 to 50 yards.
