I have available 3 packs of Sierra Match Kings HPBT 107gr 6mm projectiles (Seconds). Essentially, like the first shoot really flat 1/4 MOA verticals at 600 yds, but are the first batch production through the machines. Selling for $379/500 projectiles at Rebel Gunworks, I will take $285/500 for mine plus post.
Sierra MatchKing bullets have very thin jackets and are held to exacting tolerances in diameter and weight. These Hollow Point Boat Tail bullets have a small meplat to produce a higher ballistic coefficient. Their accuracy has been acclaimed worldwide and they have been used to win more target competitions than all target bullets from other manufacturers combined. The 6mm 107 Grain MatchKing has established a reputation of extreme accuracy at very long ranges
