Here in Canada at my local gun shop they ran out of quite a few types of ammo when Canada declared a lockdown due to covid. The guy behind the counter said that so many Americans were stockpiling ammo, that ammo manufacturers didn't have much left over to sell to Canadian retailers.
It's funny, because back when Ontario was shut down completely earlier this year, it was always the old seniors who wouldn't social distance and would come right up to me to ask me questions at my workplace.
