Will 410 slugs kill deer out to 60-65 yds? I was thinking about trying to use it for short range deer gun. I was at Bass Pro Shops in San Antonio and saw the winchester 1/5 oz slugs rated a 1830 fps. Supposed to have a 8.5 in drop at 100 yds from the muzzle.
One thing to remember, that slug only weighs about 87 grains. Not much weight there. I live in a shotgun zone and would not recommend the .410 for deer. Has it been done? Sure, but I know of a lot more horror stories than success stories. Not to mention, most .410 slugs and guns are not very accurate, and the triggers on most guns are not very good.
If you must use a .410 for deer, I would limit the shots to 25 yards or less. Even then you better be able to track without the aid of a blood trail. The only .410 slug that has any merit with me is the Rottweil Brenneke 1/4oz (110 grain), and I still would not recommmend it for deer. The Rottweill Brenneke only starts with 780 foot pounds of energy at the muzzle, 502 at 25 yards, 342 at 50, 259 at 75, and 213 at 100 yards. A coyote would be the biggest animal I would shoot with a .410 slug. If you want to hunt deer with a shotgun, do yourself and the deer a favor and use a 20ga or bigger.
If you are accurate enough to hit the brain everytime at 25 yards or less, then maybe it would work successfully for you. Do yourself a favor and cut one of those .410 slug shotshells open and look at the slug first, I'm betting you will change your mind real quick.

Here is Rottweil Brenneke's sight, notice the Foot Pounds of Energy, or lack thereof.
