Just picked up a "new" Nagant revolver 7.62X38 and I'm already getting together the cash to buy another gun. I've Got $800 saved up for a rifle and $300 for a new pistol. I'm going to get a Tokarev TT-33 and one or two spam cans of ammo for it. Might have to dip into the rifle fund to get it all but I've wanted to add a TT-33 to my Russian arms collection for a wile now.
You'll like the Nagant. Get the dies and a hundred cases - with it's low power, you can load it cheap & easy forever. Fun little wheelguns! My shooting buddy even casts his own lead bullets. Great for whacking the steel spinner targets. He has the TT33, but I haven't got one yet. I do have the CZ52 - same ammo, but more modern design. He has set up to load for it too. I'm using the Hungarian SPAM can ammo - pretty hot stuff!
