The discerning marksman will find much to admire in the formidable performance of the 30 Caliber 230 grain HPBT (#2251) bullet. Crafted with precision by Sierra, this projectile stands out for its exceptional accuracy and prowess over extreme distances. Its design features a sleek .27 caliber elongated ogive, coupled with a final meplat reducing operation known as 'pointing,' which significantly enhances its ballistic coefficient. This results in superior wind resistance and velocity retention—attributes crucial for those who demand consistency from every shot.
To ensure impeccable alignment between bullet and bore, Sierra has employed a unique bearing surface to ogive junction that mirrors the 1.5-degree angle prevalent in many match rifle chamber throats. Such meticulous engineering is what sets apart MatchKing® bullets, renowned globally for their record-setting precision on competitive stages.
However, while these bullets excel at hitting distant targets with unfailing accuracy, they are not designed for most hunting scenarios. Their construction does not guarantee explosive expansion upon impact—a feature vital when pursuing game such as varmints where quick lethality is desired through lightly jacketed counterparts like Hornet Blitz or Varminter bullets.
A critical note for enthusiasts: this bullet requires a barrel twist rate of 1x8" or faster to stabilize effectively during flight. As velocities change, so too do the ballistic coefficients: registering at .800 above 1880 fps; .780 between 1600 and 1880 fps; and settling at .740 below 1600 fps.
In sum, Sierra’s MatchKing® series remains an exemplar of fine craftsmanship dedicated to delivering unparalleled performance across vast shooting ranges—ideal for competition but approached cautiously within hunting terrains.
