I am trying to get into reloading for my .300 rum, but i have gone through 2 sizing dies over the course of roughly 20 cases put through them, the first resize die was a lee.. the second(forster) got one stuck on the first resize. both dies are fubar'd i'm using redding imperial wax, at one point so much i crumpled the shoulder of the case. what is going wrong. i just want to pull my hair out right now. any help would be great, thanks.
