Georgia Arms has 180gr FMJ for $9.50/50 that I have used and found to be good ammo.
I have an Excel spreadsheet that I have been working on that shows ammo prices for a lot of vendors. I've included: dealer name, ammo type, cost/box, multiplier factor (for boxes of <50rds), cost/50, cost/500, cost/1000, S&H - added or included in price, and other info like "out of stock", "odd lot pricing", etc. I only included ammo that I buy, i.e., no lead bullets, no frangibles/exotics, etc., only in calibers that I own.
FWIW, the price on 180gr Blazer FMJ at Midway is OK, but Natchez Shooters Supply has 10mm 180gr FMJ
Blazer for $11.78/box or $11.08/box for 10+ boxes.
