I just looked at the last 4 you posted and they aren't locked?
There is a sticky for ammo when it is available that you should use when you find ammo available. It is "stuck" at the top of the ammunition sub forum.
If they are "ammo is now in stock at XYZ" then there is an entire thread dedicated to that and we don't need new ones.
Also since you have fewer than 50 posts, anything that can be perceived as trying to run up your post count without meaningful content will be deleted.
