How do i get more of this ammo? i have like none on my police pistol and i need it because im 100 in small guns.
I know theres a code tape for this but its behind a door locked by a hard locked terminal.

If theres no way to get more ammo, is there any weaapon other than the holorifle to use?

There is the Automatic rifle....if you made it to the police station you should have found at least 1-2 of them by now. The holotape for .308 ammo is lying on the floor in the men's room in the Police Station.

You can find a 9mm Pistol and Shotgun in Dean's Secret Stashes.

what level are you? your skill should be high enough to unlock at least hard if your 20 like they suggest.

I'm level 25 and I don't point a single point in science so I can't use any terminals. I only focus on combat and medicine and speech.
