First, let me start by saying I have my wife's permission to be in here. Seriously, it appears my wife is pregnant (We'll know for sure after she gets in to see the doctor.) and we're wondering if she can continue to go to the range. Our big concern is that sound/shock waves travel faster and harder (not the best word choice, but it gets the point across) through liquid. Do any of you ladies have any information on this? Thanks.
