I was reading about this problem on the Dillon casefeeder and supposedly there is some kind of baffle you can slide out to make sure the cases that are fed neck first overtravel the slot and fall base first. I have an older 650 and the bowl is total plastic. The newer ones seem to have a metal plate around a portion of the bowl. I have no such baffle, but the cartridges fall neck first if they come up that way. Any help? Also, I was trying to make a Hornady small rifle plate work, which I think I did by using plumbing washers under the plate.
