I have suspected the 7.62x25 would do well with its 86 grain fmj bullet at 1450 fps. Lots of penetration, and a reputation for splintering bones.
Unfortunately, no documented cases so far. There is one polar bear case where a 7.62x25 may have been fired in defense against a bear, but the cartridge was not specified (could have been a Nagant revolver) and rifles were also used, so it is not a documented case.
“could have been a Nagant revolver”
Good point.
