Is there a chance that mosin ammo will become unattainable or prohibitively expensive?

I just bought a 440 round surplus tin for 200 dollars and im kinda starting to regret getting into this hobby. I know we are in the middle of a big price hike with inflated ammo prices for mosins but is it possible that its just gonna keep going up until its rare and too expensive to shoot? Im worried that i just wont be able to find ammo in the future.

Or does this stuff happen frequently and will the prices come down and availablility open up?
