Sierra have come out with their GAMECHANGER bullet, which is best described as a Matchbuilt, hunting projectile. There are five options: 90-grain/.490 BC .243”, 130-grain/.510 BC .264”, 140-grain/.508 BC .277”, 165-grain/.610 BC .284” and a 165-grain/.530 BC .308”. So, pretty much all the popular calibres are catered for; doubtless the .264”/6.5mm will be of interest to the Creedmoor crowd. The design takes from their MatchKing (MK) with its long, boat tail shape, which has become near standard for long range projectiles. The build is a ballistic tip; with a distinctive, translucent green polycarbonate tip. We are told the jacket that consists of a 95/5 % copper/zinc mix, is slightly thicker than an MK and the lead core is not bonded into position. We were sent the 90-grain 6mm/243 and the 130-grain 6.5mm/.264” and, unsurprisingly, build quality, weight and dimensional consistency were excellent. As of yet, we have not done any loading, but both calibres are in the pipeline with the 6mms for a Blaser R8 in 243 Winchester and the new 6mm Creedmoor Ruger Precision Rifle. The .264” will be for a 6.5 Creedmoor (Bergara B14 HMR) and a Mauser M03 in 6.5x55 Swedish. They look promising, we shall see.
