With larger gauge MEC loaders you don't usually run into that problem until you start loading larger shot like 4's and up. The solution for me was to replace the drop tube with the one designed for larger steel pellets. I am not sure if it will work with a small gauge loader like a 410. I would call MEC and see what they say.
