You can also check some of the big sporting good reatailers too like Cabelas, BassPro etc, but they are all mostly cleaned out online. In-store I see most flavors (with restrictions on quantity of course) return to Cabelas and Fleet Farm, but some stuff like .22LR, .223/5.56 is hard to find, if you have an AK or a Mosin-Nagant variant there is plety to be had. Even the little Log Cabin place in Danbury this past Saturday had most flavors, except of course .22LR or .223/5.56. I think it is going to be a while before any bulk opportunities come back for in-store purchases, if opportunities appear for that it will likely be with the online sellers Glock listed above. I have 1k rounds of .22LR coming from Ammo To Go any day now, and I paid at least double what I should have.
As we find stuff available let's let each other know, we do a pretty good job of that already, but timing is the game now.
Happy hunting Don!
PS-Off topic, but my fever for open water fishing continues to grow, I recently swapped out my old clunky plastic tackle box for a soft-side case and have all my stuff organized (some compartments labeled) and all new line spooled on my reels. Watching fishing shows of guys hauling in mutant bass isn't dampening my enthusiasm at all!
