.22LR is tough. I got a thousand rounds from Cabellas but it took some time.
You can call and negotiate price with them as well, depending on the wait.
I got 1500 rounds of .233 20% off ad price. :^)
I still can’t find reasonably priced 22 rimfire ammo. What was $20 a brick less than 2 years ago is now $80+!
Wally World and Pro Bass near us have zipola.
I bought a PINK Ruger 22LR rifle back in January and started looking for 22 ammo. I got some, maybe 400 rounds, then it dried up. I started putting my name on lists at various gun shops on line and in August, due to my name being on a list, I got 375 rounds of CCI Mini Mag for $23.99 at USA Midway. All told, then, have 775 rounds.
I got rounds for my other defense weapons in 2012 before the shortage hit. I bought that ammo due to our country situation with Hussein running the show. I didn’t have the 22 rifle then.
