The Remington UMC Mega Pack .223 Rem 55gr FMJ delivers 200 rounds of dependable, domestically manufactured ammunition at a volume that lets you shoot without hesitation. Built from all-new Remington components right here in the USA, this .223 Remington round pairs a 55-grain full metal jacket boattail projectile with reloadable brass casing — ideal for shooters who want reliable target practice, range sessions, or training without the cost premium of specialty loads. Whether you're zeroing a rifle, running drills, or building marksmanship before competition or field season, this mega pack gives you the round count to do it right.

The 55gr FMJ-BT bullet design feeds reliably in any standard .223 rifle and delivers consistent terminal performance downrange. Remington's UMC line has earned its reputation as the workhorse cartridge for shooters who prioritize value without sacrificing quality or consistency. The full metal jacket construction keeps fouling predictable and cleanup straightforward, while the boattail design supports flatter trajectories and better ballistic coefficients — small gains that add up when you're pushing distance or seeking precision.

This four-case format (200 rounds total) is purpose-built for serious shooters: the kind who reload, who shoot regularly, who stock up on proven ammunition rather than chase the latest hype. Reloadable brass means every fired case has residual value, making this offering even more economical for handloaders. Order this mega pack and you've got the ammunition reserves to train, compete, or hunt with confidence — without rationing rounds or worrying about supply gaps.
