I purchased 1,000 55 gr FMJ .223 for $110.95 from Cabelas during a hand reloading sale in the fall of 2011. That was before I gave them a $20- off coupon. At the same time I bought 5,000 primers and if my memory serves me correctly the price was about $100- which isn't 1? a primer but 2? a primer. Sorry for my arithmetic.
What TG recommended is a great site
as is:
http://www.wideners.com/ Wideners has the best price on IMR 3031 in 8# cans but the hazmat will kill ya'. They are good guys though in that you can order powder and primers on the same invoice and only pay the one time hazmat fee. If you order them separately (Two invoices) you have to pay the hazmat fee twice. :-))
Keep an eye on the big house retailers (Cabelas, Bass Pro, Gander Mtn, etc) as they always are giving out deals if you order on line. Cabelas OFTEN has free shipping which is great for factory rolled ammo. It seems like monthly, I also get coupons from Cabelas for store only use. There is a new Cabelas in my neck of the woods and I think they are trying to drive folks into the store hence the coupons.
Bottom-line. There are deals out there; you just have to look and be patient. I hope that helps.
