Re: Cases sticking in resizer die
It's a lube problem. STP sure works but, Lordy, what a sticky mess.
If you have some Kiwi shoe wax, rub a thin coat on the entire case, especially down around the head (the Neutral/Clear wax is best to use because it doesn't stain your fingers!); it will do you a fine job.
With spray-on case lubes, it's critical to (1) shake it up good to mix the ingrediants and (2) keep shaking as you apply it and then (3) allow the carrier to completely evaporate before sizing.
