Larry, not trying to tease but when I run across a problem like this at work, it usually brings a smile to my face. The reason is unlike some problem that are murky in terms of a cause, the problem you have is easily solvable.jlow said:Jim – if your neck gives you .2615, even if your pressure ring pushes out and there is no spring back, you should still have .2610†external diameter and .2406†internal diameter, so if your shank is 0.2432, you should still have .0026†grip.
If you are not seeing any grip after the pressure ring goes through, re-measure everything, the neck external diameter, the neck thickness, and the bullet diameter. One of those numbers will tell you what is happening.
You have every piece of evidence (bushing, case neck, and bullet) in your hands. If you have the right measuring tools and the know how to use them, there is absolutely nothing stopping you from figuring out why you have your problem.
