MF Cells, 5 cells per shot
You must have the WILD WASTELAND PERK and go to tumbleweed ranch and around where you would normally find the rare gauss rifle you will find aliens in which you must kill to receive the Alien Blaster
Sadly you cannot get anymore ammo for the weapon anywhere else in tho mojave or surrounding areas :(
In my opinion Fallout New Vegas is. In Fallout NV it is easier to make caps so you can buy better wepons and ammo. In Fallout 3 It's hard to make a lot of caps in the begining making it a slow start. But is you want to test your skills play Fallout 3.
I assume you mean the ammo components, i.e. Primer, Small Pistol; Primer, Shotgun. You can get these either from disassembling ammo of the same category (Sm. Pistol, Lg. Pistol, Sm. Rifle, Lg. Rifle, Shotgun, or .50 MG) or you can buy them from various vendors. The Gun Runners have it almost all the time.
Definitely the Trail Carbine. But the ammo is hard to find, and is expensive. :)
It is most likely to be a .32 caliber rifle since it uses .32 caliber ammo
When you start at goodsprings go to the general store they'll have some guns. Also if you follow the quests someone will give you a gun and some ammo. Oh and don't forget to look for some traveling merchants.
Original weapons that the followers have ie. Charon's shotgun, have infinite ammo. If you give him a weapon like a laser rifle you have to supply him with ammo.
marlin 35 cal. lever action. rifle/ Marlin makes the rifle ,but not the ammo for it.
You can find lots of ammo for laser rifles (microfusion cells), on dead enclave soldiers. If you run around in Washington D.C., you should find bands of soldiers. Kill them and take their ammo. If you go to the brotherhood of steel citidel, in the armory you can buy ammo from the girl down in the laboratory. Hope this helps.
Lincoln's Repeater uses .44 Magnum ammo.
Need a rifle, ammo, target, tools.
