A: Hello P.S. What an inheritance! The first thing you're going to want to do is make very certain that you now own your Thompson legally. I can offer no legal advice. Second, you may wish to have a capable gunsmith make sure that it's still in full working order.
Now for the ammo. Your Thompson is chambered for 45 ACP (aka 45 Auto). (The ammo on this page is 45-70 Government, a lever-action rifle/revolver cartridge that will not function in a submachine gun.) As a military weapon, your Thompson was designed for a 45 ACP cartridge with a 230 grain full metal jacket (FMJ) bullet with a 830 to 850 fps muzzle velocity.
UInfortunately, in the wakes of the pandemic and the recent civil unrest, ammo so popular as 45 ACP 230 grain FMJ is a little scarcer than usual, and we do not have the optimal ammo for your firearm in stock. But once you find that ammo – the kind typically used for target practice – your Thompson should love it.

A: One hundred percent, this ammo will give you good brass for reloading after you've fire it.
