[QUOTE="Bart B, post: 115065, member: 5302"] I've used standard RCBS or Bonanza full-length sizing dies for different 30 caliber magnums including the .300 Win. Mag. They've had their necks lapped out to about .002- or .003-inch smaller than loaded round neck diameter so no expander ball is used and sized case necks are very straight. But I've got to use a special body only die to size the case all the way to the belt for best accuracy; regular dies don't do this. Bullets are seated with conventional seating dies. Never had any good results with any neck-only nor the popular partial sizing techniques. Accuracy at 1000 yards with this process is no worse than about 6 inches with some 5-shot groups down to a couple of inches. I've got the same accuracy with new cases whose heads are decently square with the body axis. [/QUOTE]
