Yeah really loud, scared my grand sons. It took me some time to explain that the range is made for that. Loudest full auto that I have heard ever. As the crow flies we are not that far and it is pointed in our direction according to google maps.
I think that is all LEO or MSC (military sealift command) being trained there. I had a friend that was a trainer for MSC there. So all bought and paid for by the Government.
