I am working up letters fighting local suggested quarry/range restrictions based on Caliber. Sound data shows that the intended limit of .50 Cal means almost nothing when you compare decibel ratings of various arms up to 12 guage, but i have found no data for black powder arms. Seen any on the web? I would especially like to see some decibel ratings on calibers over .50.
Time is short, i have until April 13, 2012, to respond, then the official "comment period" is over and they no longer have to pretend they are listening.
