Wilson Combat Sierra GameKing Features The Wilson Combat Sierra GameKing load is built around a 65 grain spitzer boat tail bullet a design chosen by company founder Bill Wilson as his personal go-to load for the .223 Rem/5.56 platform. At 2730 fps and 1076 ft lbs of muzzle energy the load has the velocity and energy needed for effective performance on predators and whitetail deer while still serving well in a self-defense or tactical role. The boat tail profile reduces drag in flight helping the bullet hold velocity and a flatter trajectory as distance increases. Wilson Combat states this load is suitable for 1-7 1-8 or 1-9 twist barrels covering the twist rates found on most common .223/5.56 rifles. Each box delivers a 20-round supply of brass cased ammunition giving shooters a consistent dependable option whether they are heading to the range or into the field. The Sierra GameKing bullet has a long track record among hunters for reliable expansion and accuracy on game-sized targets. Its versatility across hunting predator control and tactical or defensive applications makes it a genuinely multi-purpose load rather than a single-use round.
