After the shortages, I buy when there are deals, to make sure I don't run short. Don't have exact numbers, this is a rough estimate (and none are reloads):

9mm- approx 2 cases of Yavex (124 gr sealed primers and cases, seems to be NATO spec). These cases came in 1450, not 1000; I've used 5 boxes, so I guesstimate 2650 or so if my math is correct.
About 900 of Magtech 115 gr FMJ. A full 1000 case of S&B white box (NATO stamps on some). About 400 rds of random FMJ boxes (Herters, Aguila 124 gr, Blazer Brass 124 gr). Got a case of Magtech flat-tip FMJ on the way, Sportsman's Guide had it $194 shipped.
Maybe 25 Winchester FMJ, I don't buy a lot, I buy enough to test and then keep the rest awhile. I figure soon I will shoot these off and get another box of the same.

9 mak- maybe 2500-3000, this includes a full case of Brown Bear, a full case of Wolf, and a bunch of random (some brass GECO and Fiocchi, some Monarch/Brown Bear from Academy, and others); one box of 50 Silver Bear HPs.

About 5000 22lr, various makes, everything from Eley Match to Remington bucket... I have an old Springfield bolt action and a H&R revolver that will shoot the cheap stuff, and I use the good stuff through a High Standard.

About 2500 7.62x39, around 400 8mm Mauser, 2-300 7.65x53 Argentine, about 400 7.62x54R, maybe 200 30-30.

About 300 rds of .45 acp, 200 rds of .32 acp.
