so damned tired you wont CARE if you get shot. then fire 40-60 rds of that at ONE guy(using cover) in the HOPE that your rds will penetrate, and will HIT him (well enough to incapacitate him) REAL smart. 2 such guys and you wont HAVE 308 anymore. Likely to happen the FIRST day of shtf. cause 308 bozos are too STUPID to be using either thick cover or darkness, or a silencer.
