601 Sports in Brookhaven has about every popular caliber you could ask for, in good quantities. They have Fiocchi 230gr FMJ .45ACP $34.99/50, and this Aguila Super Extra HP .22LR for $24.99 / 250.
They have several other brands of .22LR, 7.62x39, 6.5 (not x55), plenty of .223 & 5.56. Prices reasonable for this current climate. What impressed me is the sheer quantity of what they have on the shelf.
I bought some 30.06 and 38 special ,and 308 ammo this week from Natchez Shooters and also some 243. I am still waiting to find some 380 and 270 in something that is not 50 bucks a box. Patience. I save a 50 mile round trip by letting FED-EX and UPS deliver to me.
Academy has another "insider" online order / in-store pickup on Winchester M855, 0.72 per round. 125 rd pack, limit 4 per person. If you have an Academy account or sign up for their deals you'll get these emails. Not sure if this link will work for everyone
Traveling back home after a trip out west. Stopped in Memphis and checked out the Bass Pro shop inside the pyramid. Lots of handgun ammo at good prices. Nothing for revolvers. Saw some 223, 243, and 308 on the shelf. Only reloading supplies were Berry, Sierra, and Hornady projectiles for handguns. No powder or primers.
Academy Sports in Hattiesburg had > 10k rounds of .223, plenty of 9mm & .45ACP, 5.45x 39, 7.62x39. They have 2 4' or 5' wire shelves behind the counter for ammo, the one with .223, 5.45x39, 7.62x39 was full, haven't seen this since the panic began. Limit 4 boxes on most.
