Two options. 12 Gauge pump with 00 buck HD rounds (they’re lower charged rounds designed to prevent penetration of the walls.) or that Sig you just got with night sights.
Thanks, no I was just joking with the size of the rifle in the picture.
It was actually used in the late 1800's to duck hunt.
One shot could kill 100-150 ducks...commercial hunting??
It was outlawed in the early 1900's.
Called the Punt gun.
