I'm just setting up to load .223 and ran into a snag. I have to cut the case length down to 1.745" to get the die (brand new Hornady die) to crimp the neck without collapsing the shoulder. If I leave the die adjusted to the point where it won't collapse the shoulder with 1.760" case length, the neck tension isn't enough to keep the bullet.
I have some new unfired UMC cases that are 1.750" from the factory, and I've got to be .005 shorter than that. Seems strange, especially since max published length is 1.760"
Any ideas? I'm thinking I've got a poorly chambered die but I have no way to check it.
