I like Hornady Black, but have not had to use it on any two-legged critters thank goodness. For cheap Russian ammo I like Barnaul factory stuff the best. Heavier Barnaul SP rounds perform well. FWIW, a lot of Russian HP ammo tends to perform more like FMJ, so if you ever go the Russian route I would hunt for SP vs. HP.
Is this for in-home defense or outside property defense? For general self-defense distances I don't think negligible accuracy is going to play a factor. What you need to ensure is that the ammo you go with actually functions reliably in your gun.
