Re: 338 rum stuck cases
What type brass are you using?
i was wondering if different brass (win, lapua, norma, hornady) gave you the same problem.
Like you this is the only caliber that I have issues with. (10K+ reloads/year), so I have some experience but certain learn something new each year.
I have a couple of new approaches to work on as suggest on a different thread.
lighter powder charges and shortened brass. I will see what results those changes produce. LM
