Sierra Tipped MatchKing Features The Sierra Tipped MatchKing bullet pairs a polymer tip with refined ogive geometry to cut drag and push the ballistic coefficient higher than a standard MatchKing profile. This translates directly into flatter trajectories and less wind drift at extended distances which matters most to shooters stretching their 6mm rifles past known limits. The tip also promotes smooth reliable feeding from box magazines reducing the chance of a hang up during a stage or a string of fire. A copper jacket over the lead core holds the bullet together through the stresses of high velocity launch and long range flight. At 107 grains and a .243 inch diameter this bullet demands a barrel twist of 1 in 7.5 inches or faster to stabilize properly so reloaders should confirm their rifle s twist rate before loading. Sierra packages 100 bullets per box giving handloaders enough to work up a load and still have plenty for practice sessions. While the Tipped MatchKing is sometimes pressed into varmint duty Sierra designs this line for target accuracy rather than explosive expansion and shooters wanting dedicated varmint performance should look to Sierra s Hornet or VarmintKing lines instead. For precision shooters loading for the 6mm cartridge the Tipped MatchKing remains a proven choice for the reloading bench.
