Folks piss on the .410 but it has the same power as as 10 ga

As far as individual pellet speed. The problem is twofold I think. First obviously there are not as many pellets. But to add insult to injury those fewer projectiles are forced down a smaller bore. This makes the shot column longer, exposing more pellets to the sidewalls of the bore then constriction in the choke. This can flat spot individual pellets and make them fly untrue, hampering their ballistic qualities.

The .410 is derived from the .44 WCF "shotshells" or what we would call rat or snake shot. But it works. My .510 GNR revolver shot loads ran 1500 fps for the 1/2 oz. charge! That's a pretty good hit up close, but the revolver and rifled bore really works over those pellets.
