Believer, going on a journey...
Something's still wrong with your calculations. According to mine, Kyurem-B is still OHKOed after Stealth Rock with a neutral nature: 0 Atk Ferrothorn Gyro Ball (150 BP) vs. 56 HP / 0 Def Kyurem-B: 306-362 (75.55 - 89.38%) -- guaranteed OHKO after Stealth Rock.
May write more about Kyurem-B later, but as a quick opinion, I'm not impressed by it now and never have been. It has a couple of funky niches with sub sets, but if those were ever that good in the first place, it could have easily been replaced by Kyurem. Removing Kyurem-B does absolutely nothing for OU, as it has no major impact on the meta (the Pokemon that can beat it handily are already popular: Scizor, Jirachi, Ferro), save for making it even harder to fight Drizzle. It's just another threatening Dragon with a lot of weaknesses and significant holes in its game. If anything, I am glad to hear it is far more threatening than people expected it to be now, as I wasn't expecting much from it when it dropped.
