350 Legend ballistics in brief: factory hunting loads fire 150 to 180 gr .357-inch bullets at about 2,100 to 2,325 fps, carry roughly 1,750 to 1,900 ft-lb at the muzzle and about 900 to 1,050 ft-lb at 200 yards, and drop about 9 to 10 inches at 200 yards from a 100-yard zero. That makes the 350 Legend a 200-yard deer cartridge. Chattahoochee Munitions manufactures the 350 Legend as an 18-inch CM15 AR15 rifle; this page pairs published factory figures with Chattahoochee Munitions calculations for that barrel length.

Published 350 Legend Muzzle Ballistics by Barrel Length

Winchester publishes the same two loads from 16 and 20-inch barrels, which shows how much velocity barrel length is worth.

Load	16-inch barrel	20-inch barrel
Winchester 150 gr Extreme Point	2,225 fps / 1,649 ft-lb	2,325 fps / 1,800 ft-lb
Winchester 180 gr Power-Point	2,000 fps / 1,598 ft-lb	2,100 fps / 1,762 ft-lb

Source: Winchester 350 Legend FAQ. About 100 fps across 4 inches, or roughly 25 fps per inch. The 18-inch CM15 sits halfway between.

350 Legend Ballistics Chart: Federal Published Data

Federal publishes full downrange tables with a 100-yard zero and 1.5-inch sight height.

Distance	180 gr Power-Shok (BC .245)	160 gr Fusion (BC .259)
Muzzle	2,100 fps / 1,762 ft-lb	2,300 fps / 1,879 ft-lb
100 yards	1,793 fps / 1,284 ft-lb / 0 in	1,993 fps / 1,411 ft-lb / 0 in
200 yards	1,520 fps / 924 ft-lb / -9.4 in	1,712 fps / 1,041 ft-lb / -7.3 in
300 yards	1,292 fps / 668 ft-lb / -34.1 in	1,463 fps / 760 ft-lb / -26.6 in
Wind, 10 mph at 200 / 300 yards	8.9 / 21.6 in	7.4 / 17.8 in

Sources: Federal 350 Legend Power-Shok and Federal 350 Legend Fusion. Federal lists a 1,600 fps minimum expansion velocity for the Fusion bullet, which it holds to about 300 yards.

350 Legend Ballistics From the 18-Inch CM15 (Calculated)

Chattahoochee Munitions does not publish chronograph data for calibers it does not load. The table below is calculated: the 180 gr Power-Shok at an estimated 2,050 fps (the midpoint of Winchester’s 16 and 20-inch figures), Federal’s .245 G1 BC, standard atmosphere, 1.5-inch sight height and a 150-yard zero, which suits deer hunting.

Distance	Velocity	Energy	Path	Wind (10 mph)
Muzzle	2,050 fps	1,680 ft-lb	-1.5 in	0
50 yards	1,893 fps	1,431 ft-lb	+1.6 in	0.5 in
100 yards	1,743 fps	1,214 ft-lb	+2.2 in	2.2 in
150 yards	1,603 fps	1,027 ft-lb	0	5.1 in
200 yards	1,473 fps	867 ft-lb	-5.6 in	9.4 in
250 yards	1,355 fps	734 ft-lb	-15.2 in	15.2 in
300 yards	1,251 fps	625 ft-lb	-29.6 in	22.6 in

With a 150-yard zero, the bullet stays within about 2.5 inches of the line of sight out to about 175 yards, the practical point-blank range for a deer-size vital zone. Confirm with your own rifle and ammunition before hunting.

What 350 Legend Ballistics Mean for Hunting

Deer: energy and expansion velocity hold to about 200 yards. Read 350 Legend for deer.
Wind: 9 to 10 inches of drift at 200 yards in a 10 mph crosswind; hold for it past 150 yards.
Bear and elk: Chattahoochee Munitions does not recommend the 350 Legend. Use the 375 Raptor or 458 SOCOM XL.

Subsonic 350 Legend Ballistics

Hornady publishes a 250 gr Sub-X 350 Legend load at 1,050 fps from a 16-inch barrel. Chattahoochee Munitions treats the 350 Legend CM15 as a supersonic rifle and makes no subsonic cycling claim for it. For subsonic hunting, the 300 Blackout vs 350 Legend comparison covers the trade-offs.

350 Legend Ballistics FAQ

How far does a 350 Legend drop at 200 yards?

About 9.4 inches with Federal’s 180 gr load and a 100-yard zero, or about 5.6 inches with a 150-yard zero from the 18-inch CM15 (calculated).

What is the effective range of a 350 Legend?

For deer, about 200 yards with a good expanding bullet. Federal’s 160 gr Fusion stays above its minimum expansion velocity to about 300 yards, but drop and wind make shots past 200 harder.

What twist rate does 350 Legend use?

1:16 is the common twist, and Winchester notes it stabilizes a wide range of bullet weights. Every Chattahoochee Munitions 350 Legend barrel is 1:16.

Does a longer barrel help 350 Legend?

Yes. Winchester’s data shows about 100 fps more from a 20-inch barrel than a 16-inch barrel.

Who makes an 18-inch 350 Legend AR15?

Chattahoochee Munitions manufactures the CM15 350 Legend semi auto rifle with an 18-inch 1:16 barrel, plus Cobalt Kinetics Green and FDE Metallic Cerakote versions at Hall of Legends.
