Yes, totally legal, you just need to pay for a tax stamp and file some paperwork then wait for approval. The real limit on personal artillery ownership is the expense, the fact that most arms dealers won't sell to civilians, and the difficulty of aquiring ammo of any kind. Any explosive ammo needs, per round, a 200$ tax stamp, approval from the atf that can take up to a year, as well as special storage requirements that usuallt have to be approved by the fire marshall. I think you also need an explosive's license in a lot of places, and again, basically no one will sell to you anyway.
