[QUOTE="MagnumManiac, post: 2133762, member: 10755"] It is understood that the amount of grip is only about .001”-.0015” once the bullet is seated, no matter how small you make the neck. The condition of the brass also has an affect, hard brass resists spring back and stretching, this may result in harder seating forces but the brass itself won’t be holding the brass any tighter. It is thought that bullet tension increases over time, hence why bullet weld occurs, but lubing the necks with graphite eliminates this. Brass under tension over time can become brittle, known as age cracking and a few other names. It’s not just one size fits all when it comes to neck tension...actually resistance fitting. Cheers.
