The challenge, Get the weakest weapon in the game that take hollow point ammo, switch the game to very hard and dont take any drugs stims or anything, dont wear anything, then try and kill the legendary deathclaw, recap:
No stat boosters
No normal ammo
No companions
Only the weakest weapon to take hollow point ammo. (I dont feel like finding it out )

If you complete this you are a fallout god.

The weapon should be a silenced 22LR pistol. Hollow point rounds only, if you want to you can use a BB gun instead, including the kid BB gun

Or you could try killing it with bean-bag shells... :mellow:

Well, we might as well just try taking a piss on the damn thing.

I just tried this (in a controlled fashion) and it took me about 500 .22 rounds and 350 BBs. First I shot it until the .22 broke, then I switched to the BB gun. When it broke I brought out the law, the Abilene Kid, and it made short work of the final 350 HP it had left with all that crit damage it does.

I did find a neat bug. When the .22 broke, and I switched to the BB gun, the x1.75 ammo effect stayed on. My BBs were acting like hollow points. You could do this on purpose with AP firing weapons, say a varmint rifle, then switch to one that has no AP, say the Survivalist's Rifle, and gain the AP benefits. Or JHPs or JFPs or JSPs or whatever effect you want to put on an ammo it can't usually be on.

-gunny out.
