I know this isn't fresh, but wanted to point out Buffalo Bore's 200gr .40S&W 'outdoorsman' round, designed for animal protection.
If curious, check out this link:
.40 S&W Outdoorsman by Buffalo Bore
I carry a 4" GP100 with Buffalo Bore heavy .357Mag ammo [180 grain], which produces something over700 ft/lbs of muzzle energy from a 4" barrel. That is about what a weak .44mag load is producing, but I don't have to pack my 7.5" SRH everywhere!
However, humans, cougars, coyotes and black bear are the largest predators in my neck of the woods.
When in the area described 2 years ago I still kept the GP100 with this ammo selection and didn't feel hopeless. I had bear spray and the GP100 if the bear spray didn't work.
Even if I don't buy their stuff much, I respect the fact that Buffalo Bore has velocity/energy charts AND identifies the measured velocity from their sample guns, with barrel length measured.
The .357 Mag ammo I just mentioned looks to be about 730 ft/lbs of energy from a 4" barrel, but it looks like the same load would come out into the low-mid 800s [840s?] in a 6" Ruger GP100.
This easily trumps the .40S&W or .357Sig cartridge powers [low 400s to mid 500s in ft/lbs?]
I bought another brand of ammo that claimed to be in the 800s, but was actually in the 500s from a 4" gun, despite being recommended for bear.
I love the full disclosure of BB's sight. YMMV
