None of that is shocking. Anyone who has used these rounds can back the findings. If I was already so invested in 223 and 308 I would probably switch to something in the 6mm arena

Yep, been a big fan and vocal proponent of DocGKR's findings ever since he started posting on Arfcom back in the mid-2000s.
