As other ammo prices are coming normal like ; 50rnds of 9mm for 17.99 but 6.5 Creedmoor still so expensive. Is it because of demand & supply?

In 2021 ammo demand is low as compare to the 2020. As ammo is coming back in-stock & prices are also falling but still demand is low. I am not pretty sure but still want to know is it happening in the ammo industry?
