Shootinfool,
I just happen to have some 7828 (albeit IMR original) that I can try. A whole can that's set around for at least a year now. Just have to get some Bergers ordered in. Will do that now!....thnx....JohnnyK.
Let me know how it works out. It was recommended to me by walt berger to try the retumbo powder also as it is a favorite of the 7mag shooters. Good luck!
