Archie,
Do you have an FFL-01 or 03?
If so, or have someone in your shooting circle who does , the Black Hill Shooter Supply is a good source of brass IMHO.
1-800-289-2506
www.bhshooters.comThey have a minimum order of $50. Their price includes shipping.
Price for 221 Fireball brass is $44.70/250. Maybe you could come up with a reguirement for a hundred other cases of anothe caliber. :-)
Oh their price per 100 for the 221 is $18.20.
If you have any further question about BHSS drop me a line. Be happy to answer any questions I can.
I've been buying brass from them for many years now.
FWIW DaveP
