I second Winchester 748. A little spendy, double base ball powder currently used by the US military (according to Winchester). Meters well, supposed to make m-16 barrels last 3 times as long or something like that. I have heard a lot of good stuff about Hodgedon, too.
Boolits are so when the antigunner googles it they don't find us!
Maybe I should spell it that way too...
