Why Steel?
Most .223 ammunition uses brass cases, but steel-cased rounds are made too – usually as cheaper practice and plinking ammunition. Steel is less springy than brass, so these cases are made to be fired once and not reloaded. That is exactly why they turn up as once-fired cases, and why we make them into keyrings.
The steel gives a cooler, grey-silver tone next to the gold of brass, and the case is noticeably stiffer.

The .223 Remington
The .223 Remington – usually shortened to .223 Rem – appeared in the late 1950s with the first AR-15s and went on sale in 1964. In the UK it is a popular fox and vermin round.
Prefer the classic gold look? The .223 Remington brass keyring is the same calibre in a brass case. For other steel-cased rounds, see the AK47 steel bullet keyring and the 7.62x54R Mosin.
