Sierra christened this round with their 55 grain BlitzKing. They could easily bill it as a match bullet, as the BlitzKing is fantastically accurate with its concentric jacket, voidless and uniform lead core, and ballistically efficient boat tail. With its 3,215 fps muzzle velocity, this round’s BlitzKing serves up a G7 ballistic coefficient in the neighborhood of 0.127.
But the BlitzKing has a secret weapon: its sharp acetyl resin tip. Not only does this improve the BlitzKing’s accuracy even further, but it also facilitates explosive terminal fragmentation as it splits apart the thin-walled jacket and then core beneath it. If the BlitzKing eliminated varmints any more effectively, it would leave no evidence behind that they had ever existed at all.
Sierra loads their BlitzKings into new production brass cases. The cases are forged according to meticulous tolerances, ensuring they reliably weave in and out of a semi-auto’s chamber. Each round receives the same primer and propellant charge to promote in-flight ballistics that beg comparison to the internal workings of a Swiss watch.
