Note: PMC does not publish muzzle velocity or muzzle energy figures in the product listing data available for this load. The ballistics table below uses an industry-typical reference velocity of 3,240 fps from a 20-inch barrel, which is consistent with published PMC X-Tac 55gr performance data appearing on third-party ballistic databases. All trajectory figures are calculated estimates and must be treated accordingly. Community-submitted chronograph readings will be added as data is received.
Note: BC values (G1 and G7) are not published by PMC for this load. A G1 BC of approximately 0.243 is commonly cited for 55gr FMJ-BT projectiles of this construction class and is used in the ballistics table below as a working estimate. This value has not been independently verified for this specific PMC bullet.
Ballistics Table
Calculated estimate. Real-world results vary by barrel length, temperature,altitude, and lot. Community submissions will provide measured muzzlevelocity for comparison.
Reference velocity: ~3,240 fps (20″ barrel). Sight height: 1.5″ above bore. Zero: 100 yards. G1 BC: ~0.243.
| Yards | Velocity (fps) | Energy (ft-lbs) | Trajectory (in) |
|---|---|---|---|
| 0 | ~3,240 | ~1,282 | -1.5 |
| 100 | ~2,887 | ~1,018 | 0.0 ← zero |
| 200 | ~2,559 | ~799 | -3.4 |
| 300 | ~2,253 | ~620 | -13.5 |
| 400 | ~1,970 | ~474 | -32.7 |
| 500 | ~1,712 | ~358 | -64.2 |
Key takeaway: At typical training and range distances of 100–200 yards, this load stays well above 2,500 fps and retains meaningful energy for consistent target impact. The boat-tail base helps resist wind deflection compared to a flat-base FMJ at extended range, though drop becomes significant past 300 yards. Shooters running carbine-length barrels (16″) should expect muzzle velocities roughly 100–150 fps lower than the reference figures shown here, which will steepen the drop curve noticeably at 400 yards and beyond. This load is best understood as a short-to-medium range training round rather than a precision long-range option.
Best Uses
Good fit:
- High-volume rifle training sessions where per-round cost matters
- Zeroing and function-testing AR-15 and M16-pattern rifles
- Carbine courses and range drills requiring reliable semi-automatic cycling
- Bulk practice for 5.56 NATO-chambered rifles where chamber pressure headspace is a consideration over .223 Rem
- Steel target shooting at ranges within 200 yards
Not the right tool for:
- Hunting — FMJ-BT construction is prohibited for deer and most big game in nearly all U.S. jurisdictions due to lack of controlled expansion
- Precision long-range shooting where published BC and velocity data are required for accurate ballistic solutions
- Self-defense or home protection — non-expanding FMJ is not optimized for terminal performance in soft tissue
- Jurisdictions with lead-core projectile restrictions (California condor zones, certain public ranges)
- Shooters who need a documented, published ballistic data sheet for competition or military qualification records
Reliability Notes
No structured submissions yet.
Based on manufacturer claims and open-source product descriptions, the PMC X-Tac line is positioned as a NATO-spec training load built to SAAMI and NATO pressure standards, which is relevant for rifles with 5.56 NATO chambers. The brass casing and Boxer primer construction are noted as reloadable by the manufacturer, which is a practical advantage for high-volume shooters who recover brass. Open-source user accounts on forums and retailer comment sections consistently note reliable feeding and ejection in standard AR-platform rifles, with no recurring reports of failure-to-feed or case separation in available open data. These notes come from manufacturer claims and open sources, not structured submissions, and should be interpreted accordingly.

Price Reality
- Typical retail range: $8.50–$11.00 per 20-round box depending on retailer and current market conditions
- Per-round cost at reference price: $0.47/round at $9.49/box
- Case pricing: When available in 1,000-round cases, comparable 55gr 5.56 NATO FMJ-BT loads typically run $0.38–$0.48/round, suggesting bulk purchasing may offer meaningful savings
- Compared to Federal American Eagle AE5.56J: PMC X-Tac at $9.49 comes in roughly $1.00–$1.50/box cheaper than American Eagle at typical retail, with similar construction
- Compared to Hornady Black 5.56: PMC X-Tac offers a significant cost advantage of approximately $5.00–$6.00/box for shooters who do not require the tighter tolerances of a premium load
- Compared to budget alternatives (Fiocchi, Magtech): PMC X-Tac sits mid-tier; budget alternatives may undercut by $0.50–$1.00/box but with less consistent brand recognition in the U.S. market
- Fair price benchmark: Paying more than $12.00 for a 20-round box of 55gr 5.56 FMJ-BT at standard market conditions represents an above-market price for this class of training ammunition

FAQ
Is PMC X-Tac 5.56x45mm the same as .223 Remington, and can I use it in a .223-chambered rifle?
PMC X-Tac is loaded to 5.56x45mm NATO pressure specifications, which run higher than SAAMI .223 Remington standards. While the cartridge dimensions are nearly identical, firing 5.56 NATO ammunition in a rifle chambered strictly for .223 Remington can generate pressure levels above what the .223 chamber is designed to handle. Rifles marked 5.56 NATO or .223 Wylde are safe to use with this load. If your rifle is marked .223 Remington only, consult the manufacturer before using any 5.56 NATO-spec ammunition.
Why does PMC X-Tac use a boat-tail bullet instead of a flat-base FMJ?
The boat-tail base reduces aerodynamic drag as the bullet travels downrange, which helps retain velocity and resist wind deflection better than a flat-base design at distances beyond 100 yards. For a training load, this means slightly flatter trajectories and more consistent point of impact in variable wind conditions compared to older flat-base M193-style FMJ rounds. The practical difference at typical range distances under 200 yards is modest, but it becomes more meaningful as distance increases. PMC uses this construction across the X-Tac line to align with modern military and law enforcement training standards.
Can PMC X-Tac 55gr FMJ-BT be used for coyote or varmint hunting?
From a legal standpoint, FMJ bullets are generally not prohibited for varmint hunting the way they are for big game, and some jurisdictions permit their use on coyotes, prairie dogs, and similar animals. However, FMJ construction does not expand on impact, meaning terminal performance on small game is dependent entirely on velocity and shot placement rather than controlled expansion. Many hunters prefer soft-point or hollow-point varmint loads for more reliable, humane results. This load is better suited to training use than field hunting applications, and shooters should verify local regulations before using any FMJ load for hunting purposes.
How does PMC X-Tac compare directly to Federal American Eagle 5.56 55gr in terms of practical performance?
Both loads use 55gr FMJ-BT bullets at comparable velocities and are built to 5.56 NATO pressure standards, making them functionally equivalent for most training purposes. The primary differences between them come down to quality control tolerances, lot-to-lot consistency, and price — Federal American Eagle carries a slightly higher brand premium in the U.S. market. Neither load publishes detailed BC data for the specific projectile used, so precision shooters relying on exact ballistic solutions will face the same data gap with both products. For general range training, the two loads are interchangeable in any 5.56 NATO-chambered rifle.
Does the 20-round box count affect the value compared to bulk packaging options?
PMC X-Tac is available in both 20-round boxes and larger bulk configurations depending on retailer stock, and the per-round cost typically decreases meaningfully in higher-quantity purchases. At $9.49 for 20 rounds, the per-round cost of $0.47 is competitive for the mid-tier training market but not as economical as purchasing in 1,000-round case quantities when available. Shooters who go through significant volume in training sessions or carbine courses will find the economics improve substantially with bulk purchasing. The 20-round box format is most practical for casual range use, function testing, or trying the load before committing to a larger purchase.
