Would someone explain this barrel to me..223/.556
The .223 Wylde chamber is a little tighter than the 5.56 NATO chamber. It's basically a compromise between the tighter .223 Remington chamber and the looser NATO-spec. chamber. I believe the purpose is to achieve a little more accuracy with rounds loaded to .223 spec., but still be able to safely shoot NATO-spec rounds, which isnt recommended for .223 chambers...It has a bit more leade in the chamber to keep pressures fron Spiking.
Hey Moose - there's an interesting discussion going on in the thread about bolt switching regarding headspace and gauges. Might you want to drop in there and give your professional opinion?
I agree with Moose's post. That is identical to what I have read on the Wylde chambering.
