I wouldn't say it's over being it's not as plentiful as it was 5 to 10 years back. I did, however, pick up 200 rounds of Winchester Super X at Wally World yesterday and also found some Remington 22 golden at my local shop (Brotherhood Arms) so got me 200 rounds of that too.
Definitely more money for these. I remember buying bricks of CCI for less than $15 back in 2000.
Would love to get my hands on some CCI Stingers but haven't seen any of that in years.
