Note on Muzzle Energy: Winchester has not published a muzzle energy figure for this load in available sources. A calculated estimate from 1,060 fps with a 200 gr projectile yields approximately 499 ft-lbs at the muzzle (labeled Calculated; see Ballistics Table). Verify against manufacturer documentation before citing for any formal purpose.
Note on BC: Neither G1 nor G7 ballistic coefficient values are published by Winchester for this load. The OTR bullet design is a standard lead-core open-tip projectile. Estimated G1 BC values for comparable 200 gr .308-diameter projectiles generally fall in the 0.270–0.330 range, but no confirmed figure is available. All trajectory data below is modeled on a mid-range assumed BC and should be treated as an approximation only.
Note on SKU/UPC: Retailer listings vary. No confirmed Winchester catalog SKU or UPC was available at time of writing. Cross-reference with the Winchester catalog or point-of-sale data to confirm.

Key takeaway: As a subsonic 300 Blackout load, this round is designed to stay below the speed of sound from the muzzle, which is its defining performance characteristic — not long-range reach. The trajectory drops sharply beyond 200 yards due to the combination of a heavy, slow-moving projectile and relatively modest BC. At 100 yards, velocity retention is still adequate for the intended role of suppressed range use. Practical effective range for precision work is best treated as 0–150 yards, where drop remains manageable and noise signature stays at its minimum. Beyond 200 yards, the steep arc demands precise holdover and the energy figures become marginal for anything beyond paper targets.
Why This Load Exists
Subsonic 300 Blackout occupies a specific niche that no other mainstream cartridge fills as neatly: a rifle-caliber round that is purpose-built to be fired suppressed, delivering heavy-bullet terminal performance without a supersonic crack. The 300 BLK cartridge was developed in collaboration with the U.S. military and special operations community specifically to allow an AR-15 platform to cycle reliably with both supersonic and subsonic loads using only a barrel change — no bolt, carrier, or lower receiver modifications required.
The 200 gr OTR bullet weight sits at the upper end of practical subsonic loadings for this caliber. Heavier bullets in the 200–220 gr range are preferred for subsonic use because they carry more momentum and resist transonic instability better than lighter projectiles pushed to the same velocity. Winchester’s Super Suppressed line is engineered with this specific operating envelope in mind — the powder charge, primer, and bullet seating are optimized to function reliably in suppressed hosts where back-pressure dynamics differ from unsuppressed fire.
The Open Tip Range designation distinguishes this projectile from hunting-oriented expanding bullets. The OTR bullet is a match-style construction where the open tip results from the manufacturing process (drawn from the base up), not from a hollow-point cavity designed for expansion. This makes it well-suited for high-volume range use and consistent accuracy, but it is not a terminal-performance hunting bullet.
Best Uses
Good fit:
- Suppressed range training and drills where noise reduction is the primary goal
- Backyard or indoor range environments with noise restrictions
- AR-platform rifles chambered in 300 Blackout with a suppressor already in the system
- Accuracy testing and load evaluation at distances of 100 yards and under
- Steel target shooting where a subsonic impact signature is preferred
- Shooters transitioning from 5.56 who want to explore the suppressed subsonic role without changing platforms
Not the right tool for:
- Hunting — the OTR bullet is not designed to expand reliably on game, and most states require expanding projectiles for deer-sized animals
- Long-range precision shooting beyond 150–200 yards, where the subsonic trajectory becomes impractically steep
- Unsuppressed use where the full ballistic potential of the 300 BLK platform is desired — supersonic loads deliver significantly more energy and a flatter trajectory
- Self-defense or duty use, where terminal performance standards require controlled expansion
- Gas-impingement AR builds that have not been tuned for subsonic cycling — reliable function is not guaranteed in all unsuppressed configurations
Reliability Notes
No structured submissions yet.
Based on manufacturer claims and open-source product information: Winchester describes this load as specifically engineered for reliable cycling in suppressed firearms, suggesting the powder charge and bullet seating pressure are tuned to the elevated back-pressure environment of a suppressed host. Open-tip range bullets of this construction type are generally associated with consistent concentricity and low variance in muzzle velocity, which supports the accuracy claims made in product materials. Some users in open forum discussions note that subsonic 300 Blackout loads — across brands — can exhibit cycling issues in unsuppressed gas-impingement rifles due to insufficient bolt carrier velocity; this is a platform-level variable, not necessarily a load defect. All notes above come from manufacturer claims or open sources, not structured submission data.

Price Reality
- Typical retail range: $19.99–$24.99 per box of 20 rounds; case pricing (typically 10 boxes/200 rounds) is not widely standardized for this SKU but would generally fall in the $190–$240 range where available
- Per-round cost at the listed price: $1.07/round
- Compared to Fiocchi 300 BLK 220 Gr Subsonic at approximately $0.90–$1.10/round, the Winchester price is competitive and within the same tier
- Compared to Hornady Sub-X 190 Gr at approximately $1.30–$1.50/round, the Winchester offers a meaningful savings for range-use buyers who do not need terminal expansion
- Compared to Remington Subsonic 220 Gr OTM at approximately $1.10–$1.30/round, the Winchester is slightly more affordable or equivalent depending on the retailer
- Fair price benchmark: $1.00–$1.15/round represents fair market value for a brass-cased, boxer-primed subsonic 300 BLK load of this construction. Prices above $1.30/round for this specific load suggest a supply constraint or retailer markup and warrant comparison shopping

FAQ
Is the Winchester Super Suppressed 200 Gr OTR suitable for hunting?
The Open Tip Range bullet used in this load is a match-style projectile engineered for accuracy and consistent ballistics, not for terminal expansion on game. The open tip is a manufacturing artifact, not a functional hollow point, and this bullet is not designed to reliably expand at subsonic velocities. Most jurisdictions also require expanding projectiles for deer-sized game, which this load does not provide. Hunters seeking a subsonic 300 Blackout load for game should look at purpose-designed options such as the Hornady Sub-X with its FTX bullet, which is specifically engineered for subsonic expansion.
Will this ammunition cycle reliably in an unsuppressed AR-15 in 300 Blackout?
Subsonic 300 Blackout loads generate less gas pressure than supersonic loads, which can cause cycling issues in unsuppressed gas-impingement rifles that have not been tuned for this operating condition. Winchester’s Super Suppressed line is specifically optimized for suppressed hosts, where back-pressure from the suppressor assists reliable cycling. In an unsuppressed rifle, results will vary depending on the gas port size, buffer weight, and spring rate of the specific firearm. Testing with your exact platform before relying on this load for any critical application is strongly recommended.
How does the 200 gr OTR compare to the more common 220 gr subsonic loads in 300 Blackout?
The 200 gr bullet in this Winchester load is slightly lighter than the 220 gr projectiles found in many competing subsonic 300 BLK offerings. In practical terms, the 200 gr bullet exits the muzzle at a slightly higher velocity (1,060 fps versus approximately 1,000–1,010 fps for 220 gr loads), which can translate to marginally flatter trajectory and slightly more energy at the muzzle. The 220 gr loads carry more momentum, which some shooters prefer for suppressor back-pressure dynamics and for pushing through barriers. Neither weight class offers a decisive performance advantage at the ranges where subsonic 300 BLK is typically used.
What barrel length is this load designed for, and does it matter?
Winchester has not published a specific barrel length reference for this load. Most 300 Blackout subsonic ammunition is developed and tested with 16-inch barrels, which is the most common configuration. Shorter barrels (8–10 inches, common in SBR and pistol builds) will generally produce lower muzzle velocities due to reduced dwell time, though the effect is less pronounced with subsonic loads than with supersonic ones because the powder burn is already complete at lower pressure. The 1,060 fps figure in the product description should be treated as a reference point that may not reflect your specific barrel length.
Is the brass from this ammunition reloadable?
Yes. This load uses brass cases with Boxer primers, which are the standard for reloadable centerfire ammunition in the United States. The cases can be resized, reprimed, and reloaded using standard 300 Blackout reloading dies. However, this page covers factory ammunition only — for reloading data, consult a current published reloading manual from a component manufacturer. Case life will depend on the number of firings, inspection practices, and the specific firearm used.
