FMJ
i know the FMJ does not expand when entering or exiting. this weekend i had the chance to shoot a hog with one and there was a huge chunk of flesh missing from the other side. maybe it was the bullet tumbling through the hog but the exit wound was huge. i was very impressed. maybe the distance of the shot had something to do with it.. it was about 30 yards. hit him infront of the shoulder in the neck area. pretty cool.
