My understanding ( as always I can be wrong ) is that most of not all of the tubular ammo was not made out of lead. As such I believe that this type of ammo is considered " armour piercing" and as such is not legal to own/posses in US for the average person.
There is also quite a bit of discussion as to the amount of damage such a bullet will do to a living body since the major mechanism of damage is cut rather then crush. I personally have no idea.
