Where do you get the socom bullets?

I live 2 mins from Missouri Bullet and they have .458 405gr lead cast I use with the socom, other then that I use Barns Hornady and Nosler 300gr. My current load for the 405gr is the same as the 300gr. using IMR 4227 30.0gr

What is the groove diameter of the socom? Is it .457 or what.

The SOCOM uses .458 dia bullets like the 45-70
