Happy late 2K subs! I pretty much stopped what I was doing to put this together for you guys, that's how much I love ya. AVGN voice Now don't take that too seriously :p
Deagle uses .44 ammo, since there's no 50 Action Express ammo type in the game. It's designed to be a hand cannon, so it packs a decent punch, about as much as an upgraded .44 revolver (and it scales with the gunslinger perk), though you can up the damage in FO4Edit if need be.
This whole video is just me showing the flashlight and shooting ghouls and watermelons by the way, nothing serious. Those watermelons (disappointingly) don't burst when you shoot them, FPSRussia lied! Lol.
