[QUOTE="woods, post: 1408145, member: 6042"] There are essentially 3 types of dies. You have the standard with the expander where the case body and neck is sized smaller and the neck is expanded back to a reasonable dimension with the expander ball when extracted back up through the neck The second and probably what most use here is one of the bushing dies. They have different size bushings that you can buy to size the outside of the neck to a specific dimension. They usually come with an expander also but most remove the expander and use without. You can get a bushing die that sizes the case body also or get one that only sizes the neck. Best to get into outside neck turning if using a bushing die since the bushing will push all irregularities to the inside. Then there is the collet die from Lee that size the outside of the neck onto a mandrel which is easily extracted from the neck without effort. This alleviates the 2 problems with expander ball dies, having to lube inside the neck and jerking the expander back through the neck which can destroy concentricity. Personally I refuse to use and expander, they suck But what concerns me is when you say that the necks are tight enough to hold a bullet after firing. This can cause issues with pressure as the neck is supposed to expand enough to allow easy egress of the bullet. A chamber neck that is pressing on the brass and binding the bullet is a no-no.
