I was out hog shooting the last 2 evenings and tried some of the newer 123gr SPBT Prvi Partizan hunting ammo in my CZ527 carbine, major bullet failures. 2 rounds just ice-picked the chest of a 300+ pound sow that I ended up killing with a 357 revolver. 1 more bullet just exploded on a head shot (140 pound boar) at 25 yards, didn't penetrate the skull at all, killed that one with a handgun shot too. This is very disappointing, I've used PPU's 123gr RNSP for years as my go to factory ammo. I've had good luck with Federal Fusion and Hornady SST ammo, guess I stick to those or my reloads with SST or Barnes bullets.
