This is a great example of a subsonic 300 Blackout round that puts all its eggs in the accuracy basket. Its 1,020 fps muzzle velocity doesn’t just mean significantly quieter performance (and excellent suppressor compatibility). It also lets the bullet totally avoid the super-to-subsonic velocity transition which causes the destabilization that destroys pinpoint accuracy.
Nosler’s Custom Competition bullet is no joke. The 220 grain projectile begins as a precision engineered hyper-concentric copper jacket, with a pronounced boat tail to reduce in-flight drag. That jacket is then filled with molten lead alloy, which hardens to form-fit to every facet of the jacket’s internal geometry. The result? Nothing less than a 0.249 G7 ballistic coefficient (G1 0.528).
This ammo’s Custom Competition bullets are seated in Nosler’s own premium brass cases, with uniform match primers and consistent charges of high-performance powder to take care of ignition. Nosler is only satisfied with their work once each round has been visually inspected!
