I was walking out of the hospital and saw a whole pallet of phone books that had gotten soaked with a weekends worth of rain. I loaded a few in the ole pickup just to shoot. Too easy not too. I know I'm not going phone book hunting anytime soon
but I wanted to see what the target bullets would do.
I had some 180 target bullets loaded so when I went to the range to practice I taped six of the books together and let'er rip at 100 yards. I can't remeber but the total distace of penetration was well over12 inches.
Kinda a FYI. Whether you find this useful info depends. It doesn't change my attitude or use for the bergers.
