Ever since Federal introduced the 7mm Backcountry, handloaders have been asking the same question: what powder do we load it with? Hodgdon Powder Company is proud to introduce the answer. Accurate High Country, the newest smokeless powder in the Accurate lineup, is the powder for reloading the 7mm Backcountry. It is also a true magnum rifle propellant that refuses to choose between versatility and raw performance, delivering both in a single canister. It is built on the latest propellant technology and it is made in the USA.
High Country is a double base spherical powder. The spherical grains flow smoothly through a powder measure, which means consistent charge weights and uniform velocities from your bench. A progressive burn rate curve keeps velocity high both at bullet exit and downrange, and the double base formulation delivers an energetic, clean burning load. Every lot is produced under an ISO 9001 certified quality system, so the consistency you see shot to shot carries over canister to canister.

The Answer for 7mm Backcountry
The 7mm Backcountry is unlike any cartridge that came before it. Instead of traditional brass, it uses a one piece steel alloy case that Federal calls Peak Alloy, and that stronger case lets the cartridge run at 80,000 PSI, well beyond the roughly 65,000 PSI of typical modern magnums. The payoff is magnum velocity from shorter, lighter barrels.
After a global propellant search, Accurate High Country delivered the best ballistic performance for the round, with an ideal balance of burn speed and barrel wear.
The powder's lower flame temperature is a critical part of that fit. Steel cases have a different heat sink than brass. High Country burns at a lower flame temperature than other magnum rifle powders, making it an ideal partner for both the case construction and the pressure this cartridge operates at. That lower flame temperature also means less energy converting to muzzle flash and muzzle blast.
RCBS has developed reloading dies for the 7mm Backcountry as well. Keep in mind that the process for reloading the steel case is completely different from a conventional brass case, so refer to the published instructions before you begin.

One Powder for a Full Rack of Magnums
High Country covers an impressive spread of magnum rifle applications. It is an excellent choice in proven cartridges like the .243 Winchester, .270 Winchester, and .300 Winchester Magnum. Pair it with Winchester bullets and primers, and your handloads can duplicate the performance of Winchester factory loaded ammunition. Its consistent metering and ignition characteristics translate directly into the accuracy these cartridges are known for.
Modern magnums are equally at home. This powder is ideal for the 6.5 PRC and .300 PRC. High Country throws remarkably consistent charge weights, which leads to uniform velocities and pressures. The progressive burning of the grain provides a softer ignition, and softer ignition supports greater accuracy.
