Randy,
It depends on what you are paying now wether it will double or not.All I can say is, yes it is an upward spiral due to the increasing price of minerals.BUT we can all still catch a cold.Yesterday I was offered my regular brand of shells at 33% discount due to them being 'old stock' when I enquired what 'old stock' was I was told that the manufacturer had identified a problem with primers that was causing a decrease in performance.
This was no consolation to me as I have 6,000 'old stock'in stock.
When I mentioned this I was met with the reply "Oh don't worry they're still okay"
So I think I will buy them by the slab in future, 'just in case'.
