Federal Fusion Features The Federal Fusion 6.5 X 55 Swedish Mauser 156 gr load is built around the original molecularly bonded Fusion bullet construction that established Fusion as the first rifle ammunition specifically built for deer hunting using an electro-chemical bonding process that applies the copper jacket directly to the pressure-formed lead core to create a perfectly uniform jacket with zero susceptibility to core-jacket separation delivering the highest weight retention and deepest penetration in head-to-head comparisons against conventional jacketed hunting bullets of the same caliber. At 2 500 fps and 2 165 ft-lbs of energy with a G1 BC of 0.489 the 156 gr Fusion provides the sectional density ballistic efficiency and downrange energy retention that have made the 6.5x55 Swedish Mauser a beloved hunting cartridge for European hunters for well over a century now paired with American-engineered bonded bullet technology for enhanced terminal performance on deer and black bear at hunting distances. The skived pre-programmed nose cavity initiates consistent expansion across the velocity range typical of .6.5x55 hunting shots ensuring reliable mushrooming that transfers maximum energy on target for lethal ethical harvests without the over-expansion and fragmentation that can reduce penetration on quartering shots. For hunters who carry 6.5x55 Swedish Mauser bolt-action rifles in the field and want a purpose-built deer hunting load that matches the cartridge s renowned accuracy and terminal efficiency with the proven Fusion bonded construction the Federal Fusion 6.5 X 55 Swedish Mauser is the natural factory load choice. The 20-round box provides a practical supply for pre-season zeroing and a full hunting season in this classic and versatile cartridge which remains a popular choice in both European and American markets for deer black bear and mountain game hunting at moderate to extended distances. Federal s Fusion line is built on the principle that deer hunting ammunition deserves the same engineering investment as any other purpose-built projectile and the 6.5x55 offering extends that philosophy to one of the most accurate and historically respected hunting cartridges in the world.
