Note: Liberty Ammunition does not publish muzzle velocity, muzzle energy, or ballistic coefficient data for this specific Steel Plate & Range load on their public documentation. The ballistics table below uses a calculated estimate based on industry-standard performance data for 55 gr frangible .223 Remington loads from comparable manufacturers. All values are approximate and should not be treated as manufacturer-stated figures.
Ballistics Table
Calculated estimate. Real-world results vary by barrel length, temperature,altitude, and lot. Community submissions will provide measured muzzlevelocity for comparison.
Assumed muzzle velocity: ~3,000 fps (industry reference for 55 gr frangible .223 Rem from a 16″ barrel). Sight height: 1.5″ above bore. Zero: 100 yards.
| Yards | Velocity (fps) | Energy (ft-lbs) | Trajectory (in) |
|---|---|---|---|
| 0 | ~3,000 | ~1,099 | -1.5 |
| 100 | ~2,690 | ~884 | 0.0 ← zero |
| 200 | ~2,398 | ~702 | -4.2 |
| 300 | ~2,122 | ~550 | -15.8 |
| 400 | ~1,864 | ~424 | -37.5 |
| 500 | ~1,627 | ~323 | -74.2 |
All values marked ~ are calculated estimates, not manufacturer-published data. A G1 BC of approximately 0.255 was used as a reference value typical of 55 gr frangible projectiles. Actual performance will vary with barrel length, ambient conditions, and lot variation.
Key takeaway: At typical steel plate distances of 10–50 yards, this load carries more than sufficient energy to fragment on impact rather than ricochet. Beyond 200 yards, velocity drops into a range where frangible bullet performance on hard steel targets may become inconsistent, and the load is not optimized for long-range precision. This is a purpose-built close-range range round, and the trajectory data confirms it performs within that window exactly as intended.
The SinterFire Bullet and Why It Matters on Steel
SinterFire is a proprietary frangible projectile technology manufactured by SinterFire, Inc. The bullets are made from a compressed mixture of copper and tin powders, sintered (heat-bonded) without a lead core. The result is a projectile that maintains enough structural integrity to travel down a rifled barrel accurately, but disintegrates into fine particles upon striking a hard steel surface rather than rebounding as a coherent mass.
This design addresses a specific and serious safety problem in indoor ranges and close-quarters steel plate shooting: conventional lead-core jacketed bullets can ricochet off steel targets at dangerous angles, particularly at distances under 15 yards. The SinterFire construction eliminates that hazard by ensuring the bullet does not survive contact with a hard surface as a single fragment. The elimination of a lead core also reduces airborne lead contamination in enclosed shooting environments, which is a meaningful occupational health consideration for range staff and frequent shooters.
Liberty Ammunition’s decision to partner with SinterFire for this load reflects the growing demand for lead-free training ammunition that does not require a sacrifice in cycling reliability for semi-automatic platforms. The compressed copper-tin matrix is engineered to a consistent density that allows standard bolt and gas-operated rifles chambered in .223 Remington to cycle without modification.
Best Uses
Good fit:
- Steel plate competitions and practical shooting stages at close to moderate distances
- Indoor range training where lead exposure mitigation is required or preferred
- Facilities with no-lead policies for range ammunition
- High-volume training sessions where frangible ammunition is mandated by range rules
- Shooters transitioning to steel targets who want to reduce ricochet risk
- Law enforcement and military training environments with lead-free requirements
Not the right tool for:
- Hunting — frangible construction is not designed for reliable terminal expansion in tissue and is not appropriate for taking game
- Long-range precision work beyond 300 yards, where velocity loss and BC limitations reduce effectiveness
- Situations requiring deep penetration, such as barrier-blind engagements
- Reloading — the SinterFire case and bullet are not suitable for reloading
- Budget-focused shooters who do not require frangible or lead-free properties, as conventional FMJ in .223 Rem is available at significantly lower cost per round
Reliability Notes
No structured submissions yet.
Based on manufacturer claims and open-source product information, this load is designed to function reliably in semi-automatic rifles chambered in .223 Remington, including AR-platform rifles with standard gas systems. SinterFire projectiles are engineered to meet SAAMI pressure specifications, which supports consistent cycling across a range of gas-operated actions. Liberty Ammunition markets this line specifically for steel plate and range use, implying the load has been validated for that application. No publicly documented reliability complaints, malfunctions, or recall notices were identified at the time of publication. All notes here reflect manufacturer claims or open-source information, not structured user submissions.

Price Reality
- At $22.79 per box of 20, this load costs $1.14 per round, which is consistent with the frangible/lead-free premium in the .223 Remington market
- Conventional 55 gr FMJ .223 Remington ammunition from major manufacturers typically runs $0.40–$0.60 per round, meaning this load carries a significant frangible premium of roughly 90–185% over standard practice ammo
- Federal Syntech Range in .223 Rem (a lead-free but non-frangible option) typically runs $0.85–$1.10 per round, making Liberty’s offering slightly more expensive but delivering true frangible performance
- SinterFire Special Duty branded loads often run $1.25–$1.50 per round, making Liberty’s offering a relative value within the frangible segment
- A case purchase, if available, would reduce per-round cost — case pricing was not confirmed at publication
- $1.14/round is a fair benchmark for this load; prices above $1.40/round for this specific configuration should be considered above market for current conditions

FAQ
What makes SinterFire bullets safer on steel targets compared to standard FMJ?
SinterFire projectiles are manufactured from a compressed copper-tin matrix with no lead core. Upon striking a hard steel surface, the bullet disintegrates into fine particulate rather than deflecting as a single fragment. This dramatically reduces the ricochet risk that makes conventional FMJ ammunition hazardous at close steel plate distances. The frangible design is the primary engineering reason this load exists as a product category distinct from standard range ammo.
Is this load suitable for hunting with .223 Remington?
No. Frangible bullets are specifically engineered to break apart on contact with hard surfaces, which is the opposite of what reliable terminal performance on game requires. A hunting bullet needs to retain mass, expand in a controlled manner, and penetrate to vital organs. The SinterFire construction used in this load would not produce consistent terminal performance on game animals and is not appropriate for hunting use under any circumstances.
Can this ammunition be fired through a .223 Remington chamber in a 5.56 NATO-spec barrel?
Yes. .223 Remington ammunition is safe to fire in both .223 Remington chambers and 5.56 NATO chambers. The reverse is not always true — 5.56 NATO ammunition should not be fired in a strictly .223 Remington chamber without verifying the rifle’s specifications. This load, being a standard .223 Remington factory cartridge, presents no cross-chambering concern when used in a 5.56 NATO-spec AR-platform rifle.
Why doesn’t Liberty publish velocity or energy data for this load?
This is a common gap in the frangible ammunition market segment. Some manufacturers prioritize safety certification and range compliance documentation over ballistic data sheets for range-specific loads. The absence of published velocity does not indicate a product defect — it reflects a product category where the primary performance metric is fragmentation behavior on steel rather than downrange ballistic performance. Shooters who require precise velocity data for this load should consider chronograph testing from their specific barrel length.
How does this load compare directly to the SinterFire Green Elite .223 Rem 55 gr?
Both loads use SinterFire frangible projectiles of the same weight. The primary difference is branding and distribution channel — SinterFire’s own Green Elite line is sold under the component manufacturer’s brand, while the Liberty Steel Plate & Range load is assembled and marketed by Liberty Ammunition using SinterFire projectiles. Performance from the same bullet weight and construction should be comparable, though muzzle velocity may vary slightly depending on the powder charge and case specifications chosen by each manufacturer. Price per round is typically similar between the two.
