Last I checked there is no such "cartridge as 223 Wylde", in reality the 223 Wylde is a chamber reamer design. Bill Wylde's design was intended to enhance accuracy potential with heavier weight bullets. Nothing more nothing less. But some people are not able to discern the difference. But boy do Keyboard Cowboys, Gunshop staff, etc sure like extol the virtues with baffling people with BS.
Chamber designs
There are however two distinct cartridges in the 223 Remington and the 5.56x45.
As shown in this pdf
The biggest operational difference in the 223 and 5.56 is the pressure to which they are loaded to.

Speer (Vista Outdoors) and Federal (Vista Outdoors) have been making plated bullets for years. Their TMJ bullets are one example, and they are a quality bullet. Exceeding plated bullets from Berry's Xtreme etc.
Fusion bullets are quality bullets, only on the market via pull down ammo. They are not sold as a reloading component.
