.223 Wylde

B*omer454 said: I am just wondering what the differences between a .223 wylde chamber and a regular .223 Rem chamber are. I have heard that the throat dimensions are different. Basically the wylde chamber has more "freebore" than a regular .223 Rem. Is this correct? In a standard AR platform is brass life affected either way? Is the loading data interchangeable?

Designed by and named after Bill Wylde, this chambering was created for High Power shooters after the 80 grain .224" bullets became popular. While the Wylde chamber allows for optimal seating depth of 80 grain bullets over .223 Remington and 5.56 NATO, it is capable of accepting both ammunition types. The Wylde chamber is used by a few manufacturers who sell "National Match" configuration AR-15 rifle, barrels, and upper receivers." Loading data is the same.
