Buying ammunition by the box from the same production lot keeps velocity and point of impact consistent from one range trip to the next. Keep a record of the load you carry, check your ammunition for dents or loose bullets from time to time, and rotate your carry rounds so the ones in your firearm stay fresh. These simple habits help you get the full performance Federal builds into every cartridge.
Before you trust any new load, fire enough rounds through your firearm to confirm it feeds, fires and ejects reliably and that the point of impact matches your sights. Full-power loads produce more recoil and muzzle blast than typical range ammo, so practice with the Federal 338 Lapua 300gr SMK BTHP until you are comfortable with it, and store the rest in a cool, dry place in the original box.
The .338 Lapua Magnum was developed in the late 1980s as a long-range sniper cartridge able to defeat body armor at 1000 meters. It has since become one of the premier extreme long-range cartridges for military, law enforcement and civilian precision shooters, capable of pushing heavy bullets accurately well past a mile in skilled hands.
