Has anyone tried to make thier own BB bumpers using a 3" bumper for better visibility at longer disatances? Using the metal insert from the original BB bumpers I don't have the tools or skill to make those myself. My idea was to take a 3" bumpers put the insert in it and as close to perfectly centered as I could and fill the rest of the bumper with expanding foam. Would this be too heavy and make for very short throws or could it work? Those BB bumpers are very hard to see past about 150 yards unless you have the perfect background.
