A new thread with the subject would prolly be a better place to discuss this. I posted this issue a few times when I was going through my 9mm reload check and 40SW reload check. I seem to have a bullet off center issue most easily seen on the 9mm, less so on the 40's but still present. Ditto on the 45's. Separate tool heads holding the dies. All dies tightened down while a case is in all stations. Cases are checked after sizing and they appear to be perfect. All finished rounds are within or at spec. Issue must be presented during the flare or the seating step. I contacted Dillon and obtained an platform alignment tool which I have done twice. No major difference pre/post alignment. Off-center appears to be in the same spot every time. Dillon 650 Lee Resizer Redding Pro Comp Seater Lee crimp What do we think?
