he prospect of long-range shooting opportunities motivates hunters to purchase rifles chambered in 7 mm Rem. Mag. Its external and terminal ballistics at extended distances, though, depends on far-sighted decision-making. The recipe below was prudently planned to maximize the effectiveness of the cartridge at prodigious distances—even in areas prohibiting lead-projectile loads. Using a nearmaximum charge of Alliant’s Power Pro 4000-MR propellant, the aerodynamic, all-copper (sans tip) Barnes Long-Range X Bullet attains a sizzling 3122 f.p.s. from a standard 24" barrel. And, thanks to its 0.486 G1 ballistic coefficient, when zeroed at 250 yds. the bullet will impact 2.2" high at 100 yds., and 13.5" and 30.1" low at 400 yds. and 500 yds., respectively, thereby minimizing scope adjustments (or compensation). It’s ideal for hunting deer-size game in open areas. Elk aren’t immune, either; at 500 yds. the bullet still possesses 1,558 ft.-lbs. of energy. To be frank, within the realm of 7 mm Rem. Mag. pursuits, there’s not much this load cannot do. —AARON CARTER, FIELD EDITOR
