A .410 has the same hitting power per pellet as a 12 gauge, just less shot, otherwise they would be useless.
a .410 is a very useful shotgun, frequently carried by older guys to cut down on weight and recoil. They do very well with it to the point that there are .410 skeet leagues.
It is a good gun. Seriously good.
One of the advantages of the .410 is that you can buy your first single shot deer gun (in .410) at Walmart for about $85.00. Not a bad investment for venison. Gets the kids shooting and those who can’t afford a Remington 700.
