[QUOTE="Ian M, post: 21198, member: 25"] Brent, When you are talking penetration frontal diameter becomes a major consideration - and velocity is what creates mushrooming in most bullet designs. If you shoot a 180 grain A-Frame bullet (or most other bullet designs) horizontally into a water tank at .308 Win. velocities and at .300 Win. mag velocities the .308 Win. will always penetrate farther since it does not have as much impact velocity so it does not mushroom as large and therefore sheads energy slower. I have seen the test tank at Swift and they told me that is how it works. That might explain your results? ian [/QUOTE]
