Nope, it's still 102 maximum.
Mhm. Exploud isn't meant to be bulky. It's Hp aside, its defensive stats are crap and his typing is mediocre at best. He's meant to wallbreak with that set.
Ferrothorn works fine, although you may want to rework the spread 252 Hp / 48 Def / 208 SpD Relaxed is the standard for Ferrothorn. Also, leads mean nothing in 5th gen, thanks to Team Preview. I personally perfer Ferrothorn to Skarmory because of Iron Barbs and the resistance to Water-type attacks.
