I just bought 1000 rounds from Dale's link. Thanks! Also, I may have to investigate Wolf. $212 is almost half the price and I don't shoot enough rifle to make wearing out the chamber/throat area a real worry and I don't reload 5.56 (yet) so I really don't need the brass.
If someone will bring some extra Wolf to the C4 shoot I'll buy some from you and see how it runs.
