I use a Marlin 1895 .410 for homestead chores and home defense. I keep a modified choke in it and shoot #6. I get lots of snakes and skunks with us and our neighbors all having chickens. The .410 shotshells are probably the hardest to find ammo right now. The gun holds 5 rounds if IRC. Whenever I find shells again, I might load them progressively, shell 1-3 #6 and the last 2 shots 000
