P 270 Cal (.277) 175Gr Sierra TGK GameChanger

 The Perfect Blend of Match-Grade Accuracy and Deadly Terminal Performance.



Sierra’s new 175 gr Tipped GameKing is designed to be tough and used for heavy duty hunting work. It will hit like a hammer on big game from the great 270 Winchester as well as be right at home in any magnum cartridge. It will use a 1-8” or faster twist rate to stabilize because of its long length, but the BC’s are also extremely high because of that. The higher BC’s make it very efficient in flight so it will give a high impact velocity at distance.



Coming out in 2018 from Sierra is the GameChanger hunting bullet. It is the perfect combination of Sierra's legendary match accuracy coupled with deadly penetration. Sierra re-engineered their legendary MatchKing® bullet into a hollow point design for quick expansion and fitted it with a transparent green tip for ballistic uniformity. Inside, the GameChanger features a unique construction that utililizes a special lead alloy surrounded by a tough copper jacket that delivers excellent penetration and expansion at a verity of ranges. It's a GameChanger on any hunt!

The GameChanger features include:

Synthetic tip for smooth chambering, improved aeroballistic flight and instant expansion on impact.
Tuned ogive for industry-leading BC.
Boat tail design for stable flight and accuracy.
Open pocket (hollow point) design expands lead core instantly on impact.
Precisely engineered jacket wall concentricity ensured the most accurate bullets on the market.
Optimal jacket wall thickness controls expansion and retains weight.
This bullet requires a barrel twist rate of 1×8” or faster.
