My local indoor range has gotten rid of their dustpans for scooping up brass. I thought I would get a small dust pan and whisk broom to take with me. As I was thinking about this I thought about drilling some holes in the dust pan or trying to cut some slots in it to cut down on the dust and .22's. Has anyone else tried this and if so what size holes, slots, etc. are best. Or does something like this already exist and i just haven't found it yet?
