At the range, I typically train at 3, 5, and 7 yard intervals and quickly make mince of the target. Wide choice of ammo. My favorties are #4 .410 shotshells for snakes and varmints in the field. For self-defense I prefer Federal's .410 000 Buck (4 ball load) as well as Remington's .410 PDX load pictured below. It's really nasty and NO JOKE !!
Winchester makes the PDX < /nit picky freeper gun guy> ;)
