a .410 shotgun isn't a "power performer" ...so I'm a little puzzled where you're going with this ? I'm suspecting english is a 2nd language for you / so maybe we're just missing something in how I'm reading you ...
Shotguns are commonly available in 12ga, 16ga, 20ga, 28ga and .410....and at least in the US, there are a lot of shells available for each gague. As you go down in gague / the ounces of shot you can shoot drop. So where a typical 12ga load is 1 1/8 oz of shot ....the typical 20ga load is 7/8 oz, typical 28ga load is 3/4oz, and .410 is 1/2 oz...
But a pellet coming out of a 12ga gun at 1200 fps / delivers the same energy as a pellet coming out of a .410 gun at 1200 pfs ( there are just fewer pellets in a .410 shell / and the pattern is smaller )....
Are you looking for Defense ?
Are you hunting / if yes, what kind of game ?
Are you shooting clay targets ( Trap, Skeet, etc )
