Only medium I ever played with was hogs. 3 times it happened that 2 pigs standing behind their mommy flopped dead after a load of 2-3/4” #3 buck passed thru the old girl. 200# or so up front and 40-75# behind. All shots were broadside on the sow.
As a pig eradicator, that's efficient!
Unless you have to go chasing wounded pigs.
I used buck shot on beaver control and dropped down to smaller shot sizes (2, BB, etc.). Much better kills and I didn't watch the buckshot skipping across the water so far.
