The .350 Legend is a highly capable straight-walled cartridge that generally delivers 1- to 2-MOA accuracy in quality rifles. Shooters utilizing modern bolt-action platforms or well-built AR-15s can realistically expect 1.25-inch to 1.75-inch 5-shot groups at 100 yards when firing premium supersonic hunting ammunition. Accuracy is most heavily influenced by ammunition consistency, the rifle’s chamber tolerances (since the cartridge headspaces on the case mouth), and the bullet’s poor aerodynamic profile, which makes it highly susceptible to wind drift beyond 150 yards. While supersonic loads provide the flattest trajectory and best practical accuracy for hunting, heavy subsonic loads are also available for exceptionally quiet, short-range suppressed shooting.

Understanding .350 Legend Accuracy
Accuracy is measured in Minute of Angle (MOA), an angular measurement where 1 MOA equals approximately 1.047 inches at 100 yards. If a .350 Legend rifle is a true 1-MOA gun, its bullets will strike within a 1-inch circle at 100 yards and a 2-inch circle at 200 yards under perfect environmental conditions.
When evaluating accuracy data, the number of shots fired per group dramatically changes the results. A 3-shot group primarily demonstrates the mechanical alignment of the rifle’s barrel and scope when cold, but it lacks statistical significance. A 5-shot group introduces barrel heat and slight shooter fatigue, providing a much more realistic measurement of how the rifle will perform during a hunting scenario. A 10-shot group exposes the maximum dispersion limit of the rifle and ammunition combination. Because a 10-shot group captures a wider spread of variations, it will almost always be substantially larger than a 3-shot group fired from the exact same rifle. When researching .350 Legend group sizes, 5-shot groups provide the most reliable benchmark.
Manufacturer accuracy claims often rely on 3-shot groups fired from pristine test barrels in climate-controlled tunnels. Independent testers use 5-shot groups from field-ready rifles in natural weather conditions. This is why a manufacturer might advertise a load as “sub-MOA,” while independent testing from publications like Outdoor Life records a 1.42-inch average.
Typical .350 Legend Accuracy
Because the .350 Legend is a straight-walled cartridge, it headspaces on the mouth of the brass case rather than a defined shoulder. This design inherently makes achieving extreme precision slightly more difficult than with necked rifle cartridges like the 6.5 Creedmoor, but it remains vastly more accurate than traditional shotgun slugs.
- Factory AR-15s: Standard AR-15 platforms chambered in .350 Legend typically produce 1.5 to 2.5 MOA with factory ammunition. High-quality barrels from makers like Faxon or Shaw can shrink AR-15 groups down to 1.25 MOA with preferred loads.
- Hunting Bolt-Action Rifles: Bolt-action rifles inherently feature stiffer actions and fewer moving parts than semi-automatics, maximizing accuracy. Rifles like the Winchester XPR or Ruger American Ranch routinely produce 1.15 to 2 MOA 5-shot groups, and can print sub-MOA clusters with their preferred ammunition.
- Single-Shot Rifles: Budget-friendly break-action rifles, such as the Rossi LWC or CVA Scout, generally hover around 1.75 to 2.5 MOA. They are mechanically accurate enough for deer hunting inside 150 yards but rarely deliver true precision-rifle group sizes.
- Short-Barreled Rifles (SBRs): The .350 Legend performs exceptionally well in short barrels (9 to 12.5 inches). While SBRs lose velocity, their mechanical grouping ability at 100 yards remains virtually identical to 16-inch rifles.
Best .350 Legend Ammo For Accuracy
Ammunition selection dictates .350 Legend accuracy more than almost any other variable. The cartridge utilizes .357-inch diameter bullets, which have poor ballistic coefficients (they are short, wide, and blunt). Loads featuring polymer tips generally offer the best aerodynamics and tighter groups downrange.
| Ammunition | Bullet Weight | Type | Supersonic / Subsonic | Reported Group Size | Distance | Best Feature | Source |
| Winchester Super X | 180 grain | Soft Point | Supersonic | 1.12″ avg (5-shot) | 100 yards | Heavy bone penetration | Outdoor Life |
| Winchester Deer Season XP | 150 grain | Polymer Tip | Supersonic | 1.42″ avg (5-shot) | 100 yards | Flat trajectory / AR reliable | Outdoor Life |
| Winchester Copper Impact | 150 grain | Copper Solid | Supersonic | Sub-MOA potential | 100 yards | Deep penetration / Accuracy | Ammo.com |
| Barnes VOR-TX TSX | 170 grain | Monolithic | Supersonic | 1.69″ avg (5-shot) | 100 yards | Maximum weight retention | Outdoor Life |
| Federal Non-Typical JSP | 180 grain | Soft Point | Supersonic | 2.06″ avg (5-shot) | 100 yards | Consistent expansion | Shooting Times |
| Winchester Super Suppressed | 255 grain | Open Tip | Subsonic | ~2.00″ avg (5-shot) | 100 yards | Ultra-quiet performance | General Data |
No single load is universally the most accurate. However, the 150-grain Winchester Deer Season XP and Copper Impact loads are widely considered the benchmark for tight groups and reliable feeding in AR-15s. The polymer tips streamline the frontal profile, marginally improving accuracy and retained energy at 150 yards.
Supersonic vs Subsonic .350 Legend Accuracy
The .350 Legend was designed primarily as a high-velocity hunting cartridge, but heavy subsonic loads have been developed for suppressed applications.
- Supersonic Accuracy: Bullets weighing between 145 and 180 grains travel at speeds of 2,100 to 2,350 feet per second. They exhibit flatter trajectories, punch through wind better, and offer superior accuracy out to 200 yards. Shooters looking for the tightest groups and most predictable drop for hunting must rely on supersonic ammunition.
- Subsonic Accuracy: Bullets weighing around 250 to 255 grains travel just below the speed of sound—roughly 1,060 feet per second. While subsonic rounds can still group around 1.5 to 2.5 MOA at 100 yards, their trajectory is incredibly steep. The massive bullet drop makes ranging calculation errors highly unforgiving, effectively destroying practical accuracy beyond 100 yards.
Barrel Length And .350 Legend Accuracy
Because the .350 Legend utilizes fast-burning powders inside a straight-walled case, it achieves a near-complete powder burn quickly. A longer barrel does not inherently make the rifle more mechanically accurate, though it does provide a flatter trajectory.
- 9 to 12.5 Inches: Highly maneuverable for AR pistols and suppressed setups. Supersonic velocity drops significantly (losing up to 250 fps compared to a 16-inch barrel), which increases bullet drop and limits the effective hunting range to roughly 150 yards. Mechanical accuracy remains excellent.
- 16 Inches: The undisputed sweet spot. It offers the best balance of maneuverability, velocity (roughly 2,250 to 2,325 fps with 150-grain loads), and barrel stiffness. A 16-inch barrel is just as accurate as a 20-inch barrel at typical hunting distances.
- 20 to 22 Inches:Maximizes the cartridge’s velocity potential, adding another 50 to 75 fps over 16-inch options. While the extra velocity flattens the trajectory slightly at 200 yards, the longer barrel does little to improve mechanical group sizes.
Twist Rate And .350 Legend Accuracy
Twist rate—the distance it takes for the rifling to complete one full rotation—is a critical factor for accuracy, particularly for a cartridge that fires both 145-grain and 255-grain projectiles.
- 1:16 Twist:This is the industry standard for the .350 Legend. A 1:16 twist perfectly straddles the line, providing enough gyroscopic spin to stabilize heavy 255-grain subsonic bullets while not over-spinning light 124-grain or 145-grain FMJ target loads, keeping everything impressively accurate across the board.
- Faster Twists (1:14 or 1:12): Occasionally utilized in custom setups specifically designed to shoot heavy subsonics. For the vast majority of shooters, deviating from the 1:16 standard is unnecessary and offers no accuracy benefit.
Bullet Weight And .350 Legend Accuracy
- 124 to 145 grain (Target Loads):Designed primarily as budget-friendly Full Metal Jacket (FMJ) ammunition for range use. While they recoil the least, they often produce slightly wider groups (2 to 3 MOA) simply due to bulk-manufacturing tolerances.
- 150 to 180 grain (Hunting Loads): This is the optimal weight class for the cartridge. Polymer-tipped 150-grain bullets generally produce the tightest groups and flattest trajectories, while 180-grain soft points trade a slight amount of trajectory for deeper penetration. Both weights easily hold 1.5 MOA in a good rifle.
- 250 to 255 grain (Subsonic Loads):Built for quiet operation. They offer excellent mechanical precision inside 100 yards, but their practical accuracy rapidly degrades past that distance due to a rainbow-like trajectory.
Effective Accuracy Range
The .350 Legend is a specialized short-to-medium range cartridge. Its aerodynamic limitations become painfully obvious as distance increases.
- 50 Yards: Absolute precision. Quality rifles will easily punch overlapping holes. Bullet drop is non-existent.
- 100 Yards: The ideal zero distance. Supersonic ammunition routinely delivers 1.25 to 2 MOA. Subsonic ammunition hits with similar precision but drops significantly from the bore line.
- 150 Yards: The sweet spot for maximum practical range. With a 100-yard zero, a 150-grain bullet drops roughly 2 to 3 inches. The cartridge remains highly accurate and lethal.
- 200 Yards: Mechanical accuracy begins to suffer from wind drift. A 150-grain bullet will drop roughly 7 to 8 inches, while a 180-grain bullet will drop nearly 10 inches. 200 yards is the absolute maximum ethical range for the cartridge.
- 300 Yards: The bullet drops nearly 30 inches and sheds too much velocity for reliable expansion. The .350 Legend is not practically accurate or effective at this range.
Factors That Affect .350 Legend Accuracy
While many variables influence bullet flight, the following have the greatest practical impact on .350 Legend accuracy:
- Ammunition Consistency: Because straight-walled cartridges headspace on the case mouth, minute differences in brass length or crimp pressure dramatically alter accuracy. Premium ammunition mitigates this.
- Wind Drift: The blunt, flat-nosed .350 Legend bullets have terrible ballistic coefficients (often under .250). A 10-mph crosswind will violently push the bullet off target past 100 yards.
- Barrel Quality: A heavy-profile or match-grade stainless steel barrel minimizes harmonic variations and heat-induced point-of-impact shifts, which is especially important on AR-15 platforms.
- Trigger: A heavy, gritty 8-pound trigger will cause the shooter to pull the rifle off target. Dropping in a 3.5-pound match trigger is the fastest way to shrink group sizes.
.350 Legend Accuracy With A Suppressor
The .350 Legend makes an outstanding suppressor host, significantly taming both the mild recoil and the muzzle blast.
A quality suppressor will rarely degrade the rifle’s mechanical accuracy; in fact, the added weight often dampens barrel harmonics and slightly tightens group sizes. However, threading a suppressor onto the barrel will cause a Point-of-Impact (POI) shift. The bullets will remain highly accurate, but they will strike a different location on the paper than they do unsuppressed. Shooters simply need to note their suppressed zero and adjust their optic accordingly.
Manufacturer Data vs Independent Testing
When researching .350 Legend accuracy, shooters must distinguish between laboratory claims and field realities.
Ammunition manufacturers test their loads in heavy, rigid universal receiver barrels bolted directly into concrete blocks indoors. This entirely removes wind, shooter fatigue, and platform variables from the equation, resulting in advertised sub-MOA capabilities.
Independent reviewers test ammunition in consumer-grade AR-15s and bolt-action rifles shot from a benchrest outdoors. Because of real-world variables, a load that claims 0.75 MOA in a lab will routinely print 1.5-MOA 5-shot groups in independent field testing. Shooters should prioritize large-sample independent testing when setting expectations for their own rifles.
Best .350 Legend Setup For Accuracy
For the shooter looking to extract the maximum practical accuracy from the .350 Legend, the ideal configuration is:
- Rifle:A premium bolt-action (like the Winchester XPR) or a well-built AR-15 utilizing a match-grade barrel (like Faxon or Shaw).
- Barrel:A 16-inch free-floated barrel featuring the standard 1:16 twist rate.
- Optic: A Low-Power Variable Optic (LPVO) such as a 1-6x or 1-8x, or a traditional 3-9x hunting scope featuring a customized drop-compensating reticle for straight-walled cartridges.
- Ammunition: Winchester 150-grain Deer Season XP or Winchester Copper Impact for the flattest trajectory and tightest supersonic groups.

What is the most accurate .350 Legend ammo?
Supersonic loads utilizing 150-grain polymer-tipped or monolithic bullets consistently provide the tightest groups and flattest trajectories.
Is .350 Legend accurate at 100 yards?
Yes. 100 yards is the ideal zero distance, where the cartridge is highly capable of holding tight, ethical groups.
Is .350 Legend accurate at 200 yards?
Mechanically, yes, but practically, it struggles. The blunt bullet suffers from wind drift and drops roughly 7 to 10 inches, making 200 yards the extreme outer limit for hunting.
Are subsonic .350 Legend rounds accurate?
Subsonic rounds (like the 255-grain loads) are mechanically accurate at 100 yards, but their steep trajectory makes them practically inaccurate past that distance unless the shooter perfectly estimates range and holdover.
Are supersonic .350 Legend rounds more accurate?
Yes. Supersonic rounds fly much faster, which flattens the trajectory and reduces wind drift, making it far easier for the shooter to hit the target at varying distances.
Does barrel length affect .350 Legend accuracy?
No, a shorter barrel does not ruin mechanical accuracy. A 10.5-inch AR pistol barrel can be just as mechanically precise as a 20-inch rifle barrel at 100 yards, though the longer barrel provides more velocity and less drop at distance.
Does twist rate affect .350 Legend accuracy?
Yes, but the industry standard 1:16 twist is universally used by manufacturers to perfectly stabilize everything from 124-grain FMJs to 255-grain subsonics.
Does a suppressor affect .350 Legend accuracy?
A suppressor does not degrade group sizes, but it will shift the point of impact on the target due to the added weight altering barrel harmonics.
What bullet weight is most accurate in .350 Legend?
150-grain polymer-tipped bullets are universally considered the most accurate supersonic option, offering the best balance of velocity, stability, and trajectory.
Final Verdict
The .350 Legend is an impressively accurate cartridge that perfectly fills the legislative need for straight-walled deer hunting ammunition. Shooters can realistically expect 1.25- to 1.75-MOA accuracy from standard factory rifles using premium supersonic ammunition, which easily outperforms traditional shotgun slugs. While subsonic loads offer an incredibly quiet shooting experience, the cartridge is at its best when pushing 150- to 180-grain supersonic bullets.Because its blunt projectiles bleed velocity rapidly and succumb to wind drift, the .350 Legend’s maximum practical accuracy is strictly limited to 200 yards. For hunters operating in dense timber or across small fields, a 16-inch .350 Legend paired with polymer-tipped ammunition delivers exceptional, repeatable precision.
