Seems I read somewhere about some shotgun loads supposedly invented by the Brits who used them in Malaya. It was either 00 buck or #4 buck with all the "dead space" between the balls taken up by #6 birdshot. I don't think anyone manufactures these commercially, but anyone ever tried such a load they loaded themselves? I know that Aguila makes a mini-shell that is a combo of #1 and #4 buck. I wonder how well those work. Any thoughts?
