@Podmonkey . Your boy made a few videos on the solid copper bullets. The first one is .380 and 9mm on a meat target. The second one was a .40 through a car door into a meat target. Even he had to admit their good performance through barriers even though i believe he tried to skew the results by using .40 since a 9mm hollow point wouldn't have done as much damage after the car door.
