In agreement with Mart and stumpkiller. I have hunted deer for fifty years and used many calibers, and read all those tests in the old days. Some bullets of some sectional densities and velocities were said to be marginally better than others, and then another test would change the results, Have had bullets or shotgun slugs bore through stuff I never saw and flatten the deer, next time a twig would send the same off into orbital velocity. Clear shot is the answer. Good smoke, Ron in FL
