300 Win Mag Ballistic Performance

Trajectory & Wind Drift

The 300 Win Mag drives heavy 190gr match bullets at 2900 fps, producing a noticeably flatter trajectory than the 308 Winchester at all distances. At 1000 yards the 190gr SMK drops approximately 280 inches with a 100-yard zero. Wind drift in a 10 mph crosswind reaches about 60 inches at that distance — substantially less than lighter, lower-BC cartridges.

Energy & Terminal Performance

With 190gr match loads the 300 Win Mag retains over 1500 ft-lb of energy at 500 yards and remains supersonic well past 1200 yards. The cartridge is a proven choice for elk, moose, and large African plains game. Hunting bullets in the 150–200gr range deliver reliable expansion and deep penetration across a wide range of game sizes.

300 Win Mag FAQ

What is the effective range of 300 Win Mag?

With heavy match bullets (190gr Sierra MatchKing at 2900 fps), the 300 Win Mag remains supersonic past 1200 yards and retains over 1000 ft-lb of energy beyond 700 yards. For hunting, most shooters consider 600-800 yards the practical limit depending on bullet selection and conditions.

Is 300 Win Mag good for elk hunting?

The 300 Win Mag is one of the most popular elk cartridges in North America. With 180gr bonded hunting bullets at 2960 fps, it delivers over 2000 ft-lb of energy at 400 yards — well above the 1500 ft-lb threshold most hunters use for elk. See our 308 vs 300 Win Mag comparison for a detailed ballistic breakdown.

How does 300 Win Mag compare to 6.5 Creedmoor?

The 300 Win Mag delivers significantly more energy at all ranges but produces roughly twice the recoil of 6.5 Creedmoor. For target shooting and deer hunting, 6.5 CM is more pleasant to shoot. For elk-sized game and beyond, the 300 Win Mag's energy advantage is decisive. See our 6.5 CM vs 300 Win Mag comparison.

How much does a 300 Win Mag bullet drop at 500 yards?

With a 190gr Sierra MatchKing at 2900 fps and a 100-yard zero, the 300 Win Mag drops approximately 38 inches at 500 yards under standard atmospheric conditions. This requires roughly 7.3 MOA of scope adjustment. Use the calculator above to compute exact values for your specific load and conditions.
