I’ve been loading .300 and 7mm Roy’s for years. I have never used anything by Weatherby brass and just use the neck sizing die for practice rounds and full length size or new cases for hunting. Some of my 7mm Weatherby cases have over 10 firings and never had a case neck split or head separation. Not so with 7mm Rem Mag cases. BS...
