Actually it really does not live up to that claim. Sure it has the potential to be just as lethal... And there dead certainly is dead...
But the ability of the .410 to do this instantly certainly is not equal to the .73 caliber shotgun...
Killing is not the intent while it certainly can be a side affect of
stopping the threat which is the actual purpose of deploying a firearm in self defense...
I want my threats stopped right now... For this I prefer the payload be weighed in ounces rather than grains
...
As for folks with the need for the lighter recoil may need to resort to a .410 but need to consider any and all limitations due to such a smaller payload...
