I think Grand chariot can be debatable, seeing as how the spell is basically a bunch of light beams coming out of seven magic circles. I mean he deflected a barrage of Erza's swords, so maybe it is possible. But I agree with you on that he can't reflect Sema(it's a freaking meteor). He didn't show he was capable when he faced off against Jellal in the Tartaros arc.
