Today’s topic of discussion is What Is The Difference
between .223 Wylde and 5.56 NATO AR-15 Barrel.
First and for most, let’s get the terminology straight. .223
Wylde IS NOT your regular .223 Remington! I know, both sound very much similar
but these are completely different animals. So let’s go into details.
5.56 NATO and .223 Remington
Though they share identical case dimension, they are
slightly different and thus, are not the same cartridge.
.223 Remington is slightly smaller than your standard 5.56
NATO. As we can see from the picture above, the throat of the 5.56mm bullet is
slightly longer than that of the .223 Rem. Thus, it is ok to fire .223 rem
rounds from the 5.56 chamber but it is not ok to fire 5.56mm rounds thru .223
Remington chamber. It will simply cause pressure problems.
To avoid this issue, Bill Wylde (and hence the name, .223
Wylde), had an idea to create a chamber that would clear both rounds, 5.56 NATO
and .223 Remington. Hence, .223 Wylde was created – a chamber that takes
advantage of both of these loads. In other words, .223 Wylde combines the excellency
to handle both rounds in one source, the hotter 5.56 rounds without pressure
concerns and .223 rounds that offer edge-on accuracy that’s so common for Remington
rifles.
Logical question – If I can fire .223 Rem out of 5.56 NATO
chamber, why should I care about .223 Wylde? The answer is simple. While yes,
there is no issue to use .223 Rem in 5.56 NATO, however, if you are looking for
tighter groups, you will want something with a tighter throat that .223 Wylde
chamber offers – or simply put, a slightly tighter freebore diameter (.2240
freebore diameter). Thus, .223 Wylde is known for extreme accuracy. And as we
all know, better accuracy equals more versatility, and that’s what we,
enthusiasts, are always looking for.
