One of my bosses has cleanly killed deer and bear with 410 000 before he quit hunting. Some other locals keep a 410 and some assorted ammo by the back door and have never failed to deal with pets from woodchuck to coyote. My better half's old bedside 410 did well (24"+ so halved to over the 12" minimum of gel) in water jugs with 3 or 5 pellet loads. The + at the end of the penetration was the norm but how much it represents is buried in an archived notebook I'm not fishing for. That plus clear gel and shenanigans leaves me with little need to see a "real" gel test. Someone is roughly getting a cylinder dump of something between 32 S&W Long and 32 H&R Magnum when hit by a 000 buck load. In almost every shotgun I've seen the stuff patterned in, even the Flite Control fans would be happy to 10 yards or more.
Going back to controllability, a buddy's gun enthusiast daughter has been wheelchair bound and partially bedridden between hospital stays for the last couple years. Her 410 mini-Shockwave patterns well to 10+ yards, she won't be fighting outside the house to lengthen the range, can physically handle the gun and recoil from her various real life positions, and gladly does dry work with it even when confined to the bed. She has a shotgun as she insists on always owning, keeps it handy around the place, and her dad buys more buck whenever she runs low so she doesn't need to be precious with it on range trips as health allows. Her lesser half works nights and everyone involved appreciates the little shotty on top of her carry 22 WMR snub. My recoil and muzzle blast averse wife liked even a flyweight 410 enough to do quality bead sight work using the buck and Brenneke slugs out to 25 yards. Anything being a bother in the direct line of sight of our house at the time was in range for an airing of grievances.
