I have been checking the Federal site for a while for 45ACP 185gr FMJSWC ammo, in the last month the price has gone up 12.5% on that load. It was $63.99/50 in October, in November it jumped to $71.99.
Inflation may raise the price of ammo over the next year, and likely shipping costs.
That may somewhat be offset by increased supply.
It seems like most common ammo has increased in supply in the last 3 months with Remington getting back into full production and several other ammo companies have increased production capacity.
