At 20-30 yds #3 buck will pass through a 250# boar on a broadside shot to the chest and kill other hogs standing behind it. Did the 3’fer thing, uh, 3 times up in GA about 25 years back. Keep the occupied rooms and neighbors in mind when you start shoot heavy buck in a house. Birdshot will halt the debate w/o putting innocents at risk. For that matter, birdshot will put a deer down instamundo at 10-15’.
