Generally, you're limited to firing 6 rounds or less per day during training due to blast & shockwave effects. The guys we trained with didn't have that much ammo on hand, anyway, but interesting to know.
It's loud when you are the loader/spotter or are standing close by. It's not loud at all if you are the one firing it (with your head practically on the tube). That is my experience anyway.
Not loud at all but it gives you a distinctive feeling like you've been slapped in the base of the skull by God. The Carl G was the first thing that came to my mind when I read the article.
The CG is LOUD. Wicked backblast on that, too.
