Re: Rust in my dies
If the rust is of the light surface variety on the seater, you can probably salvage it with a little steel wool and some light oil. In the sizer, anything more than that could be a problem. From your description, I'd take a long hard look at that die and see if it's going to be problem with regard to scratching the brass, that sort of thing. If there's pitting, I'd toss it without a second thought. Sizing dies are available separately, and even gives you the option of upgrading to something like the Redding Type -S bushing dies.
