[QUOTE="mtJim, post: 2607432, member: 121886"] It is plenty of neck tension, .004 right now. I didn’t even measure prior to annealing, since there were no issues and it was looking good and shooting good. I haven’t yet shot these few reloads since annealing and reloading, but I know I didn’t have this sticking issues prior to annealing/resizing/prepping. I usually don’t have my dial indicator setup on my concentricity gauge, but I will spin a loaded round just for visual. These latest reloads have a visible wobble, something I never noticed before. It’s just a bad picture the wonky looking stuff. The shoulder is a smooth radius, no step. The most likely cause of the scratches is from having the rounds previously loaded and stored in the MTM ammo box bullet down. I tore those rounds apart and resized with the new chamber. Also since got new ammo boxes. The bullet is definitely misaligned, making the case mouth look out of square. I couldn’t measure anything out of square on the mouth, at least to .0005. I am with [USER=7999]@RockyMtnMT[/USER], my thinking is the softness of the freshly annealed brass and the high neck tension is causing the bullet to wobble. And hopefully this will also resolve itself after the first firing. [/QUOTE]
