It will eventually come down, but it's going to take some time. I've seen reloadable brass 9 MM under $10.00 a box. And .45 ACP under $14.00. Those are pre Obama prices. Lead shot is right around $30.00 @ 25 pound bag. Which is also down from $50.00+ during the Obama administration.
As was mentioned, .22 ammo is all over the map, because amounts are all over the map. 325, 500, 525, and 550 round bulk boxes are everywhere. Then you have the Remington 1,400 round, "Bucket-O-Bullets". So you have to figure everything back to a price per round, in order to be able to do a realistic comparison.
Another thing are all the different grades of .22 ammo now available. You have bulk, Mini Mag, and other high velocity. Then you have the ultra high velocity stuff like Stinger's and Velociter's. Then you have all the subsonic and novelty ammo like CB Long, 60 Grain Agulia, Colibri primer powered loads, Piney Mountain Tracer Loads, and the like. If that isn't bad enough, you also have all of the high end target ammo, that can run higher than most center fire per round. I've seen ultra premium .22 L.R. target ammo as high as $20.00 @ box of 50.
All of this makes pricing extremely confusing from back in the days when you bought either Winchester Western / Super X, Remington / Peters, or Federal by the 500 round brick. And it was all within a few cents of each other.
