Re: Anyone still use Thunderbird 2208?
I did a Bing Search for Thunderbird 2208. At the Cast Boolits website forum, there is a thread in the "Canister and Surplus" category discussing this powder.
In short, it's a surplus powder used for .223 Rem or 5.56NATO, .308 Win and .30-06. Check over there for contacts, not much loading information posted.
For loading generic .308 and .30-06 loads, if the price was right, eighty pounds would be very useful.
