I took a small doe with a .410. The shot was about 30 yds and the deer was feeding. Good solid lung shot, but the deer acted as though it wasn't hit. I was just about to shoot again when it fell over. Did the job I guess, but not quite to my satisfaction. Never deer hunted with the .410 again.
i knew a guy who butchered a deer years ago and found a what looked like 410 slug buried in the deers shoulder from past years. i would never use one for deer. if recoil is an issue there are better low recoil rounds like 20 guage slug or 44 mag.
