The .223 Rem
Remington developed the .223 in the late 1950s alongside the first AR-15 rifles, and released it commercially in 1964. The military 5.56x45mm NATO grew out of it – the two look almost identical, though the military round runs at higher pressure.
In Britain the .223 Rem is a workhorse: a common choice for foxing and vermin control, and legal for muntjac and Chinese water deer in England and Wales with a suitable bullet. Plenty of UK shooters own one as their first centrefire rifle.
Light Enough to Forget
Fired .223 brass is brought back to a bright finish and resized so a bullet can be seated – it looks like a loaded round but is completely inert. A 25mm split ring completes it. At about 57 mm long it adds very little weight to your keys.
Brass or Steel?
Prefer a steel case? The .223 Remington steel cased keyring is the same calibre in a steel case instead of brass. Other small-calibre rounds: 5.56×45 NATO, .222 Remington and .22-250.
