Most people know that in a .44 mag chamber, you can safely shoot .44 Spl. and .44 Russian. Likewise, in a .45 Colt chamber, you can shoot .45 Schofield and the .45 'Cowboy'. The latter is a case designed for CAS which is the same length as a .45 ACP but with a .45 Colt rim.
I looked at the case specs for .44 Russian and 44-40 and Lo!, the .44 Russian case is withing a couple of thou of a 44-40 up to where the shoulder starts, the 44-40 being a bottle neck case with a slight taper. The .44 Russian chambers just fine. The next thing to do was to shoot some and see the results.
Accuracy was excellent, grouping at the same POI as 44-40s with the same 200 gr LRNFP. Recoil was negligible, rapid recovery between shots. No wonder people like shooting the .45 'Cowboy' in .45 Colt revolvers!
The slight difference in rim diameter was a concern, but primer hits in Pietta 44-40 SAAs was dead centre and you'd need a micrometer to detect any case deformation. By feel and to the naked eye they appeared unchanged and they would easily resize back to original specs.
I was assured by the mavens on the Cas City forum that doing this would result in babies dying and birds falling from the sky. That just ain't so. I don't necessarily recommend this, but it works.
Years ago The late Major (R'td.) George Nonte wrote articles on doing such things when specific brass was unobtainable. Likewise General Julian Hatcher enjoyed shooting .380 ACP in P-08s and P-38s, operating the actions by hand to eject cases. It pays to experiment.
