Federal Barnes LRX 7mm Backcountry 168gr FMJ Rifle Ammo - 20 Rounds - Federal's 7mm Backcountry is an entirely new high performance, all-range cartridge that reinvents ammunition as we know it. It not only provides superior ballistics and terminal performance, it does so through compact, shorter-barreled suppressed rifles. Barnes LRX Armed with a high ballistic coefficient, polymer tip and unique nose cavity, the all-copper Barnes LRX takes down tough game at both close range and extended distances. Ballistically Best Powered by Peak Alloy case technology, 7mm Backcountry can be loaded to higher chamber pressures than brass case counterparts. As a result, it produces higher muzzle velocities than comparable cartridges, retaining that velocity downrange for less drop and wind drift.
