Description and Performance

The original Winchester factory load consisted of a 275-grain (17.8 g) bullet at 1,480 ft/s (450 m/s).[1] This straight-walled cartridge case was designed for black powder rather than smokeless powder.

Besides the Winchester 1895 lever-action, the .38-72 WCF was chambered in the Winchester 1885 single-shot rifle.

With the introduction of superior cartridges designed for smokeless powder, the .38-72 WCF became obsolete and was soon dropped as an optional caliber for the Winchester Model 1895 and 1885 [3] Production of loaded cartridges by Winchester ceased in 1936.

gollark: This is, well, homelab-*adjacent* at least, so I figure I might get some help here: how can I copy my ebooks from Amazon Kindle (the service, I lost my actual physical Kindle) to Calibre? I can access them in the "cloud reader" thing and the Android app (on a rooted device, and also one old enough that it seems okay with storing some app data on SD cards), but have no idea how to import the files stored on there.
gollark: The Gallery app often works okay?
