.308 and .223 at Twilight

I was in the mood for some nitrocellulose therapy this evening, and with the days still being short (sunrise today: 9.42a, sunset: 4.06p), I thought I'd wait for it to start getting dim to see if .223 put on as dramatic a show as .308 hitting steel.

Sadly, for .223, this wasn't the case, but .308 didn't disappoint.
