Lots of very good premium ammo available for the 300 RUM and 7mm STW. The Rum has gotten to be so popular even small mom and pop shops tend to carry it these days.
As long as you have an internet connection, have 24-48hrs and are within the CONUS you can get whatever you want.
There are also several custom loaders whom will tailor a load just for your rifle if you like.
