My Sniper char usually was (can't remember for sure)
SPECIAL: 6, 8-10, 4-6, 3-4, 8, 10, 6
Traits was gifted and small frame.
Tag skills usually was small guns, talk, First Aid.
Perks you can see what I recomend in another thread.

(if you go so low charisma make sure to get magnetic personality to get that extra party member - you can then have a party of 3 NPCs - mostly for carrying stuff or when you need to keep multiple enemies bussy)
But keep pumping up small guns untill they reach about 140-150 ish.
When you can get the perk "Tag" select Energy weapon (I think it is called) and pump that up to 140-150+
This guy can kill most any one monster in 1 action round and most often 1½ per action round in the end-game.
