I think you misunderstood. I'm not trying to use the 3.5s for home defense. I just got a box of em cause I haven't shot one before. After I put three in the tube I was just curious if a 2.75 would fit afterward. Anyhow, these high velocities don't really kick alot harder than low recoils (or not that I notice). For home defense you wouldn't need high capacity anyway unless a gang broke into your house. I'm pretty sure five buck shots will do the trick but I'm just stoked I can fit six now.
p.s. The turkey loads kick like a m/f for anyone who hasen't shot one. Kicks tons harder than my .300 weatherby mag. They're hella fun to shoot but too spendy to just go out and blow a bunch of rounds.
