Sierra MatchKing Features The Sierra MatchKing 105 grain bullet in 6mm is engineered around Sierra s benchmark manufacturing tolerances producing a copper jacketed projectile with a hollow point boat tail profile that holds a very small meplat for enhanced ballistic efficiency. That tight meplat keeps the bullet s drag low and its flight predictable which is exactly what long-range shooters need when wind calls and elevation corrections must be trusted shot after shot. The boat tail base further reduces base drag stretching the bullet s effective range and flattening its trajectory downrange. Reloaders chasing repeatable five-shot groups benefit directly from the thin consistent copper jacket that resists deformation during seating. Every MatchKing bullet is held to a weight tolerance of plus or minus 0.3 grain and a jacket concentricity of 0.0003 inch maximum variation specifications that keep velocity spreads tight across a loaded batch. This consistency is why MatchKing bullets have set the standard for competitive accuracy for decades among bench rest and high-power shooters. The 100-count box gives handloaders enough material to develop and test a load without running short mid-session. Sierra notes these are match bullets and not intended for most hunting applications making them best suited to paper target and steel competition use.
