Did a search for 300 SAV dies and NOBODY has any, not Midway, Natchez, the owner did say he had 2 boxes of 180 grainers, but they were expensive...
Whatever that means...
It means that there were probably pretty expensive . I used to carry factory Remington 180's in Maine if I didn't have the time to make my own .
Last time I was in your neighborhood it was purposely driven for bullets , powder , and primers . Likewise at Autumn Gun Works .
