The 223 Wylde vs. 223 Rem isn’t a cartridge comparison. Instead, it’s a barrel chamber comparison. As you continue reading this article, you’ll discover what makes them different and which one is the better option for your next AR-15 build.
223 Wylde vs. 223 Rem: What’s the Difference & Why Does It Matter?
Unlike the 223 Remington, which is a rifle cartridge and barrel chambering, the 223 Wylde is only a barrel chambering. Bill Wylde designed the 223 Wylde for NRA High Power competitors who wanted improved 223 Rem accuracy out of a 5.56 NATO-compatible chamber, according to Armory Life.
The 223 Remington chamber has a 0.040″ throat, 0.2240″ throat diameter, and 3.10° leade angle. The 223 Wylde chamber has a 0.078″ throat length, 0.2242″ throat diameter, and a shallower 1.25° leade angle. The 5.56 NATO chamber has a 0.070″ throat length, 0.2265″ throat diameter, and a 1.20° leade angle.
Essentially, the 223 Wylde chamber splits the difference between the 5.56 and 223 Rem. It combines 223 Remington chamber’s tighter .224” throat diameter with a leade angle closer to that of the 5.56 NATO chamber.
These dimensions allow the 223 Wylde to handle the higher pressures of the 5.56, which are dangerous in a 223 Rem chamber. SAAMI sets 223 Remington’s maximum average pressure at 55,000 psi. However, 5.56 NATO military-spec ammo often reaches 62,000 psi.
It’s safe to fire 5.56 ammo in a 5.56 or 223 Wylde chamber, but not in a 223 Rem chamber. Only 223 Rem ammo is safe to fire in a 223 Rem chamber.
Why Choose the 223 Wylde?
Here are the reasons to choose a 223 Wylde chamber for your next rifle.
• Ammo versatility: Safely fire 223 Rem and 5.56 ammo.
• Better accuracy: Fire 223 Rem more accurately than a 5.56 chamber allows.
