Certain cartridges I've had my eye on for the last few months haven't moved in price at all, even as today. But I do expect that things will start to heat up soon and any number of variables can crop up and make it worse, but I definitely don't recommend waiting too long because I don't see it getting any better. Things keep popping up in my news feeds about ammo and components shortages, raw materials, etc....
I just picked up 1K rd case of brass 9mm for $250 shipped and am hoping to grab another cpl cases and a few thousand rounds of .22lr within the next couple months just to exceed my normal reserve min being an election year and all. Who knows though, but my instincts don't usually fail me on this, but certain things make it fairly predictable and obvious
