I experienced my first case head separation on a 300WM. This was the 2nd loading of the brass and I FL resized the case one to true up the factory Winchester brass. The second reload was neck sized only. I apparently have the die screwed down to much when sizing it the first time but was following the recommnendation of the die manufacturer (Lee).
I have read about using the nickel between the case holder and the die. Any concurrence to this practice.
How do I get my stuck case out? I tried putting a bore brush through to no avail. I haven't tried catching the lip with just a rod yet but seems like very low probability of success.
