[QUOTE="dok7mm, post: 1180108, member: 90080"] Simply stated. Neck tension provides the resisting force to the bullet seating operation. This is true whether using bushing dies or conventional dies w/expander ball. Consistent bullet release, upon firing, is dependent on overcoming that neck tension. The more consistent the neck tension, the more consistent the bullet release pressure (or speed). This is why most shooters put so much effort into case preparation. We sort brass, some turn necks, some anneal --- all in an effort to keep neck tension as uniform as possible and obtain lower SD and ES numbers. When you have consistency in all reloading steps + a capable rifle, the result should be much smaller groups at longer ranges. JMO [/QUOTE]
