I don't believe anyone is chambering .300 Savage at the moment, but every once in awhile Remington or Savage will do a run.
The biggest drawback to the .300 is that reloading is a pain because of the short neck and steep shoulder.
The round still sells, as there are still a lot of Savage 99s, Remington 81s, 722s, and 760s in circulation.
