NEW VEGAS!

It's the best one available, sniper-wise at least. The only other gun that does a higher one-time shot than the AM-Rifle is a special Gauss Rifle (energy gun).

If you get some .50 Cal Armor Piercing bullets, Guns +90 skill, AM-Rifle with a Sneak attack it should instakill Death Claws. Try to aim for the head, it usually gives you a solid kill. There is only one Deathclaw I know off that can survive that and its the Legendary Deathclaw.

If you take the Hand Loader perk you get access to craft some custom damage-boosting ammo types for most guns, AM rifle's .50 included. You can actually one-shot the Legendary Deathclaw with that on a Sneak Attack Critical if you've the Better Criticals perk. There's literally nothing the AM rifle can't handle in one shot under the right circumstances, but the damn ammo for it is so rare and heavy it's like far easier to use the Sniper Rifle or Gobi Campaign Scout Rifle instead. You can craft custom ammo that comes with x 1.5 or so damage for that one too iirc once you've the perk. The AM is pure <3, though it's sortaaa... impractical after a while. And its AP cost in VATS makes me Q_Q
