About this bullet
.277 | 156gr | Sako Hammerhead is a bullet made by SAKO. At 156 gr (10.1 g) and a diameter of 0.277'' (7.04 mm) it suits handloads where bullet weight and barrel length have to be matched carefully. Its G1 ballistic coefficient of 0.321 drives velocity retention and wind drift downrange — higher values mean a flatter trajectory at distance. A twist rate of 1:12.0 is recommended for stable flight; slower twists can under-stabilise this bullet. We currently list 903 load recipes across 10 calibers for this bullet.
