400 Legend ballistics in brief: factory loads fire 190 to 215 gr .4005-inch bullets at about 2,250 fps, carry about 2,350 ft-lb at the muzzle and about 1,100 ft-lb at 200 yards, and drop about 8.6 inches at 200 yards from a 100-yard zero. Winchester designed it to match 450 Bushmaster energy with less recoil. Chattahoochee Munitions manufactures the 400 Legend as a 16-inch CM15 AR15 rifle and as 16-inch and 10.5-inch uppers; this page pairs published factory figures with Chattahoochee Munitions calculations for the 16-inch barrel. The 10.5-inch 400 Legend pistol upper gives up velocity against these figures.

400 Legend Ballistics From the 16-Inch CM15 (Calculated)

Chattahoochee Munitions does not publish chronograph data for calibers it does not load. The table below is calculated for the 210 gr Power-Shok at an assumed 2,150 fps, 100 fps below Federal’s published figure (the same 16-to-20-inch difference Winchester publishes for the 350 Legend), Federal’s .207 G1 BC, standard atmosphere, 1.5-inch sight height and a 150-yard zero.

Distance	Velocity	Energy	Path	Wind (10 mph)
Muzzle	2,150 fps	2,155 ft-lb	-1.5 in	0
50 yards	1,959 fps	1,789 ft-lb	+1.4 in	0.6 in
100 yards	1,779 fps	1,476 ft-lb	+2.1 in	2.4 in
150 yards	1,611 fps	1,210 ft-lb	0	5.8 in
200 yards	1,458 fps	991 ft-lb	-5.5 in	10.7 in
250 yards	1,321 fps	814 ft-lb	-15.0 in	17.5 in
300 yards	1,206 fps	678 ft-lb	-29.5 in	26.1 in

With a 150-yard zero the bullet stays within about 2.5 inches of the line of sight to about 175 yards. Confirm with your own rifle and ammunition before hunting.

What 400 Legend Ballistics Mean for Hunting

Deer and hogs: about 1,000 ft-lb at 200 yards from the 16-inch CM15, with a heavy, wide bullet.
Black bear: Winchester lists black bear among the 400 Legend’s intended game. Read 400 Legend for black bear.
Elk: Chattahoochee Munitions recommends the 375 Raptor or 458 SOCOM XL. Brown and grizzly bear: the 458 SOCOM XL.
Wind: about 10 inches at 200 yards in a 10 mph crosswind; the low BC drifts more than the 350 Legend.
