I'll be honest, it's only very rarely that I have seen a case fail because it has spilt at the neck. I have seen signs of pending case head separation mostly in .303 Brit. All the loads I did for my 303 Brit and 7.62x54r I neck sized only and had no issues.
Maybe I haven't reused my brass enough to start seeing failures.
So if neck sizing isn't the cats meow for accuracy....when is it appropriate to neck size verses full length resize? And why is neck sizing toted by all the major reloading companies as something that increases accuracy?
