In 14Twists, the 50g Sierra Blitz king is another "match" grade bullet, sierra takes some serious time and effort to control jacket concentricity in their "Blitz King" grade bullets, and they have produced some extremely small groups in my rifles.
The jacket quality control is one reason you pay more money for the Blitz king bullets, but for serious accuracy shooters, they are worth every penny.
IN the test that another guy and I performed, the blitz king 50g was more explosive than the other poly tip bullets, great for p. dogs, ground squirrels, jack rabbits, not so much for coyotes.
