Like Springer99 said- I find a lot of them way too light and way too easy to move around. I filled the Lee one up with bullet rejects, machine nuts, and a ball bearing or two in order to give it some weight and stability. The closest thing I could find to seal it up with was copper form-a-gasket stuff. Took a while to dry, cure, set up, whatever- but it's stayed in place for 12 or 13 years now.

I'm going to use the words "clip" and "Long Colt" every chance I get. It grinds my gears to see new members attacked when we all know dang good and well what's being refered to.
