Comparison Verdict
Flatter Trajectory
308 Winchester drops 1.4" less at 500 yards (63.3" vs 64.8"), providing a meaningfully flatter trajectory for mid-range shooting. This translates to less scope adjustment and a larger point-blank range, which matters in hunting scenarios where quick shots are needed.
Energy Retention at 1000 Yards
308 Winchester retains 387 ft-lb more energy at 1000 yards (566 vs 179 ft-lb), offering greater terminal performance at extended range. For hunting applications, most experts recommend a minimum of 1000 ft-lb for deer-sized game — check the energy table above to see where each cartridge crosses that threshold.
Wind Drift at 500 Yards
308 Winchester drifts 7.4" less in a 10 mph crosswind at 500 yards (20.8" vs 28.2"), making it more resistant to wind deflection. Wind reading is typically the largest source of error in long-range shooting, so lower wind sensitivity directly translates to more consistent hits at distance.
Verdicts derived from computed data at standard conditions (sea level, 59°F, 29.92 inHg, 50% humidity). Actual results vary with ammunition, barrel length, and environment.
