Years ago I had the use of a Walther GSP-C in 32 S&W Long. OMG, that pistol was accurate! It remains the most accurate handgun I have ever fired. The guy I borrowed it from wanted me to work up loads for it using the now-out-of-print Hornady HBWC bullets. Easy enough, the lowest-listed load of WW-231 from the Hornady Manual gave right around 700 FPS and the bullets stacked atop each other.
I couldn't leave well enough alone, so I swapped in cast #313492s over that same load and primer. They shot just slightly larger groups at 25 yards. The chamber of the Walther was tight, and feeding got balky. It had a slight taper form, it turned out. The fix was to pull the decapping stem from one of my 32 S& W Long sizing dies, and run the finished cartridges in about the length of the rebated nose on the #313492. The rounds fed perfectly after that.
A few years later I find a Model 1895 Nagant revolver, and nothing would do but to make ammo for it. I scored 100 of the Starline 7.62 x 38R brass that was available for a short time, and like the GSP-C it requires bullets seated flush or deeper to function its gas seal mechanism. #313492 and its rebated nose to the rescue, along with short-sizing to 'crimp'. The loadings work, but the Nagant is an odd contraption. I have only seen one used in film, during "Enemy At The Gates"--a decent war film about the Battle of Stalingrad and Vasiliy Zaitsev. (2001) There is a scene early in the film where a Soviet officer or NCO is standing near the Volga River bank, using the revolver to shoot fleeing/deserting Soviet soldiers. War is hell on earth.
