Official-data note: Remington lists part 20107 as a 200-round package and publishes full factory velocity, energy, 10 mph wind drift, and trajectory data for the 150 gr FMJ load. The factory table below reproduces the current manufacturer data.

Manufacturer: Remington. Exact official product pages and technical documents are recorded in the editorial verification log. Any retailer-listed field is labeled.

Ballistics Table

Official Remington factory ballistics. The trajectory column uses the manufacturer’s 100-yard-zero table with sights 1.5 inches above bore.

Key takeaway: Part 20107 is the 200-round package of Remington’s 150 gr UMC FMJ load. The official specifications are 1905 fps and G1 BC 0.390.

The UMC Line and 300 Blackout’s Range Role

The Remington UMC (Union Metallic Cartridge) line has historically occupied the value-tier segment of Remington’s ammunition catalog, designed specifically for shooters who need reliable, consistent performance in large quantities without the cost premium of match or hunting-grade loads. The 300 Blackout cartridge itself was developed in the early 2010s to provide a suppressor-compatible, AR-15-platform round capable of both supersonic and subsonic performance. Remington’s decision to chamber a 150 grain FMJ in this caliber targets the growing community of AR-platform owners who use 300 BLK uppers for training and range use at supersonic velocities. This is not a subsonic or specialty load — it is a straightforward bulk training round for standard supersonic cycling.

Best Uses

Good fit:

• High-round-count range sessions and carbine training drills where cost-per-round matters
• Function testing and break-in of new 300 Blackout upper receivers or complete rifles
• Semi-automatic target shooting at distances of 100–200 yards
• Shooter development and trigger time in training environments where terminal performance is not required
• Compatibility with standard AR-15 platform rifles chambered in 300 Blackout with standard supersonic-rated gas systems

Not the right tool for:

• Subsonic or suppressed use — this is a supersonic load and will not cycle reliably in subsonic-optimized setups
• Big- or medium-game hunting where a controlled-expansion bullet is required; verify the applicable regulations before use
• Long-range precision work beyond 300 yards where trajectory and BC matter
• Varmint hunting where rapid fragmentation or expansion is required for clean, ethical kills (despite some marketing language suggesting varmint use, FMJ is not recommended for this application)
• Competitive shooting disciplines requiring match-grade consistency or tight velocity spreads

Reliability Notes

No structured submissions yet.

Based on manufacturer claims and open-source user observations, the following notes apply — all sourced from manufacturer product descriptions or community-level open reporting, not structured test data:

• Remington describes UMC rifle ammunition as manufactured in the USA, which aligns with Remington’s domestic production facilities.
• Case material, primer type, and reloadable status were not found in the verified official material for part 20107.
• Open-source community observations on 300 Blackout FMJ loads in this weight class generally report reliable feeding and cycling in standard AR-platform rifles with properly configured supersonic gas systems, though no structured extraction rate data is available for this specific SKU.
• No active recall notices have been identified for this load at the time of publication. Users should verify current status with Remington directly before purchase.
