Product Overview
Remington UMC 55gr Metal Case is Remington's budget training load for .223 Remington. "Metal Case" is Remington's term for a full metal jacket bullet, so this performs identically to FMJ offerings from other manufacturers. At 3,240 fps and 1,282 ft-lbs, it matches the M193 ballistic profile. The brass case carries Remington headstamps, and the boxer primer makes it reloadable. Shooters who already have a stockpile of Remington brass may prefer UMC to keep their reloading supply uniform.
Weekly range practice and casual target shooting are the primary applications. UMC feeds reliably through AR-15s, bolt rifles, and the Ruger Mini-14. The 0.202 G1 ballistic coefficient is lower than Federal AE (0.269) and Winchester USA (0.255), which means more bullet drop and wind drift past 200 yards. For close-range steel and paper work inside 100 yards, that difference is irrelevant. Beyond 200 yards, shooters may notice the trajectory gap compared to boat-tail loads.
UMC availability can be spotty since Remington's restructuring, though production has stabilized under new ownership. The brass quality is good for one or two reloads but tends to show primer pocket looseness sooner than Federal or Winchester brass. For shooters who don't reload and just want affordable brass-cased .223 for the range, UMC is a functional option that fills the same role as any other 55gr FMJ.
- Brass-cased and boxer-primed for reloading compatibility
- Matches standard M193 velocity and energy specifications
- Reliable feeding in AR-15 and bolt-action platforms
- Competitive pricing among brass-cased .223 options
- Lowest ballistic coefficient (0.202 G1) among the major 55gr FMJ options
- Brass quality is less durable for multiple reloading cycles than Federal or Winchester
- Availability has been inconsistent since Remington's bankruptcy and restructuring
- Accuracy tends to run 2.5-3.5 MOA in semi-auto rifles
