The 6.5, 7, 30, 338 calibers have all had really good ballistic coefficient developments for hunting bullets over the years. But the best BC's of these bigger calibers seriously drop off after 338. Will the bullet manufacturers ever see the potential market there?

I realize there are a couple boutique companies making some of non traditional construction, but I'm looking for a more traditional bonded lead type core. Nosler Accubonds for example: they make a 300 gr 338 cal but their biggest 375 cal accubond is also 300 gr. Come on.
