So far the best cure I've heard is to fill the bars with 20-gauge buckshot.
"20-gauge buckshot"?
20 gauge is the size of the shotshell, or barrel of the shotgun. Usually 10, 12, 20, 28, or .410 gauge.
Buckshot comes in different sizes such as #00, #0, #1, #2, etc.. The bigger the number the smaller the shot pellets. #4 and #5 is considered turkey shot, #6, #7, #7-1/2 bird shot, and #8 and above dove shot. Pellets can also be lead or steel, and in some cases copper.
Sorry, didn't mean to pull a Red on ya.
