I am reloading .223 for the first time, and running into a problem. The attached image shows that the shoulders are getting crushed when I am seating the bullet. They mostly look like the two on the left, but it was hard to get on camera, so I over did one to get a picture. I would like to add the the re-sizing die is RCBS, and the bullets the 55 vmax (square bottom).
My theory is the ball on the de-capping die is out of spec (under sized). There just seems to be too much force needed to get the bullet into the neck, thus crushing the shoulder. We cleaned out the neck very well and used a camfer tool to clean up the neck.
