Randy's Range Report gives us an interesting double this time, reviewing the 1895 Nagant Revolver and the Tokarev TT-33 pistol.  The Nagant is tested with both actual 7.62x38R ammunition and .32 H&R Magnum.  The metric designated ammo is the stuff actually made for this gun.  It can also shoot a variety of .32-caliber revolver ammo.  (There have also been conversion cylinders made so it can shoot .32 ACP, by the way).

The TT-33 uses 7.62x25 ammo, which in case you don't know, fires a very fast little bullet (85 grains at around 1600 fps).  What I didn't yet know is that Wolf now produces a JHP version as part of the Wolf Gold line (warning, *.pdf).  I'll have to look for some of that.

I don't have a TT-33, but I do have a CZ-52, which uses the same ammo.
