Frequently Asked Questions
Is this .223 Rem ammo safe to shoot in a 5.56 NATO chamber?
.223 Remington ammunition is safe to fire in rifles chambered for 5.56 NATO. However, the reverse is not always true — 5.56 NATO rounds should not be fired in a barrel marked ".223 Rem only" due to slightly higher pressure. Always confirm your firearm's chamber marking before selecting ammunition.
Is the 55-grain FMJ bullet suitable for varmint hunting?
Yes. The 55-grain FMJ at .223 Rem velocities is widely used for varmint control on species such as prairie dogs, groundhogs, and coyotes at moderate ranges. For hunting applications requiring rapid expansion, a soft-point or hollow-point load may be preferred, but FMJ performs reliably for high-volume varmint sessions where cost and round count are a priority.
Can I reload the brass cases from this Remington UMC ammunition?
Yes. Remington UMC ammunition uses reloadable brass cases with standard Boxer primers, making spent cases easy to resize, reprime, and reload. This adds significant long-term value for handloaders who want to stretch their shooting budget even further.
