You know that weird lip thing that comes with some speedloaders? I found that it works perfectly. You dont want to push the bbs straight down like the WE loader.. that will eventually damage the mag feed lip and can also scratch up the bbs on the way in. What you want to do is feed the bbs in the same way as they come out. I found that clip on lip that comes with the loader fits perfectly over the WE mag and works like a charm. I took one of my loaders and made it a dedicated WE loader by supergluing the lip on (it was falling off frequently).
