For gunning, the ever beloved pellet s are almost sure to hit the horns (the number hitting the horns could vary though). Normal S needs a bit of precision, and you don't always have the time against Alatreon.

On another note, Gunlance it instead (Ukanlos GL would be nice). Forward stab will decimate it when it taunts, use a fire tornado, or at the end of horn combos. Uppercut is also very good, though learning when to use it, and hitting, is a different issue.
