I can get primers and powder but its only one purchase a day. If you can find the primers and powder buy it.
With the shot don't be afraid to get number 5,7,7.5,8, and 9 shot lead it all works when you need it. Don 't depend on the 6 shot, if you can't buy, (6) it get different size.
I have reloaded number 8 shot for pheasant hunting, just used a wider choke, less shot in the bird. JMO
Its getting harder to find let alone get,
