As for 9 Makarov, there might be a fair amount of bear experience with those out of Russia. (might be harder to find with the scrotes in DC and their wars) But I would expect it’s not the recommended medicine for Russians or eastern Euro countries that use/used the Mak. And it would be nice to know if Tokarev has a record. 30 cal bullet, but screaming velocity and crazy penetration.
Also, there’s a story about some female dog musher defending her silly self with an LCP 380 from a moose a year or two ago. It failed...

MoOses Is BIG!
ONE BITE SISTER.
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.
