Any State I have hunted in it would be illegal to use. Not because it isn't "powerful" enough, a number four shot does not know whether it has been discharged out of the barrel of a .410 caliber or a 12 gauge. (Although because of the size of the payload the number four shot discharged out of a .410 could actually be travelling a little faster than it would out of a 12 gauge).

The difference of course is pattern density. In a .410 your normall using 1/2- 11/16 ounce of shot while in a twelve gauge your normally using 1 1/2-2 ounces of shot in a turkey load. It is all about payload baby!!

More than one life has been taken by a .410 at close range. Power is not an issue.
