410 slugs.
Good to 100 yards or less.
Muzzel energy = 41 mag. at muzzel.
410 guage is my favorite. I've taken more small game with this caliber [save waterfowl] than all others i've owned.
I used to use 410 slugs as a good home defense weapon [ 870 Remington] 8 slugs. [Still would if i owned a 410 guage gun.] Reasons? = Close range would be deadly, good knock down energy, explosive expansion on soft targets, over - penatration not an issue. Very low recoil, fast follow up shots if need be. Noise levels acceptable in confined areas.
12-34hom.
