[QUOTE="sinister, post: 788430, member: 9572"] Your die does not give you enough neck tension if bullets are advancing out of the case at all. If feeding from the magazine causes the inertia of the bullet to overcome your neck tension (the same effect as a body not wearing a seatbelt once the cartridge seats -- the bullet keeps moving forward until it jams into your lands). You might try a Redding (or other brand) S-die or neck-bushing die. You can get either a neck-only die or a neck-sizing full-length die. Crimping a non-cannelured bullet can contribute to a core-jacket separation, inducing wobble-about-the-axis and opening your groups. [/QUOTE]
