RE: Bird Shot Ballast?
How about using bb for bb guns. I use the brass bb as the lead one or not sold any longer do you EPA and lead in the enviroment. first ine the bilge and keel with wax paper. I then fill the are with the bb's. I then slow pour in glue tapping the side of the hull to remove air bubbles. 2 days later i flip the hull upside down the the fitted mass of bb come out. I peal off the wax paper and re insert the the weight. I make the weight mass removeable this way.
