7mm Backcountry
The 7mm Backcountry (abbrivated by SAAMI as 7mm BC) is a modern rifle cartridge developed to utilize a one piece steel alloy cartridge case patented as Peak Alloy case technology, which is able to withstand higher pressures than traditional brass alloys. According to Federal this case technology was developed in response to U.S. military solicitations. The objective is to obtain higher muzzle velocities from short-barreled rifles, which are lighter and easier to carry than the long rifles traditionally used for shooting at extended range. The cartridge is dimensionally similar to the .30-06 Springfield and its derivatives, particularly the .280 Remington and .280 Ackley Improved. Federal Premium Ammunition designed the cartridge to utilize long, heavy-for-caliber bullets due to their superior ballistic coefficients.
