Is your neck too thin...
Bullet retention in a cartridge is very important in that it has the same press fit in all re-loads to achieve the same ballistics each time. As press fit is reduced the friction is reduced, and up goes the ballistic speed of your bullet. I believe that all re-loaders should check the outer diameter of the cartridge, and categorize them into groups for consistency. I prefer not to load brass that has stretched more then .002 in thickness. This would compute to .004 on the diameter. Most new cartridge brass measures .015 in thickness, but can vary a bit for larger bullets. This is why factory ammo although not better can have more stable ballistics then re-loading ammo that is not staged by neck size. If you load different sized neck brass you cannot expect the same results at the target. Sort, and don't load thin brass for safety!
No thin necks...RIGHT!
