The Berdan-primed Russian target ammo that SOG sells for $15/40 is the anoemic 592 fps ammo I chrono-ed. Like the faster Fiocchi (A whopping 674 fps!), it requires the cartridge pushing ejector, a la a SA, due to the expanding end of the case.
I did make some measurements of the rim in the Nagant ammo and the .32-20 loads. The originals are .3874" with the case diameter just ahead of the rim at .3673". The .32-20 measures .4008" and .3478" respectively. The original Nagant ammo permits a .004" feeler gauge to fit between the fitted case's rim and the outter circumference of the ratchet. The .32-20's won't seat at all, ie, they are proud of said ratchet, unless the case is pushed aside... and, even then, not all of my cylinders' chambers will take a .32-20 case. The canted case may be problematic, too. I elected to turn down the rim ~.024" on my micro lathe, not a fun proposition... but, I only had 200 cases...
Well, the sanded headstamps, turned down rims, resized via an M1 carbine die .32-20 cases all ready, I ran into one last problem... the crimp was barely visible. The die was hitting my 550's shellplate. I had to grind the .32-20 seating/crimping die's mouth. Finally... I loaded 2.3gr TiteGroup, chosen because of it's big case/small powder volume position insensitivity (... and, it was in my only powder measure!), some 100gr .312" Meister DEWC, and small pistol primers from Federal.
Yesterday's trip to the range was fun... my trigger finger seems to have recovered from the 20+lb DA pull. The revolver worked flawlessly, a first. Additionally, the five loads of ammo (35 rounds) shot all fell out without the ejector! It was too bright and sunny to chrono, so I just shot away. The slow little pills made an appropriate 'dink' when they hit the rebounding plates, although they didn't budge. It appeared to hit a six o'clock view at 12 yd... seemed to group well. I went from the 12yd plates to some at 110yd... they hit ~10ft low on the berm. I adjusted - and actually hit the 12" plate once.
The Nagant is fun... but, is it fun enough to warrant all of my efforts? I think so... but, this is a hobby - a passtime. The revolver has no practical use... It is neat. To think, I didn't want to try the .32 H&R ammo due to the cost! Oddly, if you keep the revolver clean, no smoke escapes the b/c gap until you release the trigger... with any of the ammo's I have tried.
