Using the Lee Nagant dies, Starline 32-20 brass and Missouri Bullets Cowboy #6 (100 gr .314 dia. 12 BHN) with Unique to develop loads. Powder tested 3.0 grs to 4.2 grs successfully. Optimal accuracy load probably around 3.4 grs Unique. Barrel slugs to .3135. Not bad with bullet seated out to end of cylinder. I have more testing to do.
Tried some Russian “Sporting” ( light 83 gr wadcutter) ammo, but Berdan primed –Drat! Very light recoil, a very light load. No reloading here, it's old brass anyway.
Tried some brass from PPU (Prvi Partisan) Nagant ammo. About a quarter inch longer than the Lee converted 32-20 brass. Sizes/expands fine with the Lee die. Fits revolver cylinder, BUT loading with the 100gr .314 dia. bullet fails; the bullet as it fully seats (as an original Nagant round below the case mouth) stretches the cartridge to exceed the diameter the Nagant cylinder will chamber- it’s too fat!
Any suggestions on using full size Nagant brass from PPU? Options include (1) shortening the brass to converted 32-20 length. (2) Use an undersized soft bullet. (3) ?
