If you want some great deals on brass you may want to check this site out:
Their brass is once fired, polished, and bagged in packs of 100.
I bought 576 Brass from these folks and let me tell you, they are First Class. They are very quick to respond to any questions you might have.
Another great thing is they offer Flat rate shipping you can get up to 500-600 brass for a flat rate of 7.70. They are very quick to ship, usually the same day you order.
I bought 300 300 Win Mag for 10 cents ea, 100 7mm Rem Mags for 10 cents ea, 100 30-06 brass for 8 cents ea etc etc
They have some good 270 win brass for 6.50 per 100 as well.
That's pretty good prices for once fired and polished brass.
If they don't have what you want, just ask because they have 1000s of brass in stock. If they have what you want in stock, they will polish it and get it ready to go.
