Its G1 ballistic coefficient of 0.418 drives velocity retention and wind drift downrange — higher values mean a flatter trajectory at distance. A twist rate of 1:6.0 is recommended for stable flight; slower twists can under-stabilise this bullet. We currently list 229 load recipes across 7 calibers for this bullet.
