Got me thinkin and i remembered way back in the day a friend had a marlin carbine in 357 mag he wanted to see how much penetration it had, he had a bunch of wall board scraps leftover from a job he stacked 30 half inch thick pieces of wallboard and shot into it from just a foot or so with a factory hornady 158 grain XTP/HP we found the slug in the 26th piece it did not mushroom at all we literally could have reused the bullet. In my book thats some serious penetration. What can it not do???
