Lincoln's Repeater is located inside of a display case in the top floor of the Museum of American History offices. I use this weapon all the time against large enemies (even raiders) mostly because it's a one hit kill to the head. Lincoln's Repeater - My second favorite weapon due to the scarce amount of ammo.It's found from a woman named 'Sydney' (obviously) who you can kill (no bad karma) during the quest 'Stealing Independence'. Sydney's 10mm 'Ultra' SMG - My favorite 10mm weapon.The required materials for making this powerful mine are: 10 caps, Lunchbox, Sensor Module, and a Cherry Bomb. Plant these mines around the perimeter of a Deathclaw and it should take it down on very easy difficulty. Bottlecap Mines - The best kind of mine in the whole game, it's craftable so the supply is plentiful.The Alien Crash Site is found due north of MDPL-13 Power Station and northwest of the Greener Pastures Exposure Site.

The Alien Blaster can be obtained next to the body of a dead alien lying a few feet away from his crashed spaceship. Alien Blaster - The most powerful weapon in the game, it's effective against any enemy.The best weapons I usually use to get rid of Deathclaws are the following: Alien Blaster, Bottlecap Mines, Sydney's 10mm 'Ultra' SMG, Lincoln's Repeater, and my all time favorite- Tri-Beam Laser Rifle. I also find this weapon very useful against the tougher enemies. He meant the 'Terrible Shotgun', which is found from the merchant 'Smiling Jack' in Evergreen Mills. Just wait until you have to go into their sanctuary for the bobblehead. You find them with the enclave and in the north west of the wasteland. I can take one out with about 3 head shots with the terrible rifle (a unique combat shotgun). It depends on what lever you are and your skills.
