I probably need to expand this question. I bought my 650 last Dec. I loaded 2500 rounds of 30-06 and about 2000 .223. I then needed to size, decap and trim about 4000 30-06. This went well, only had a couple of feeding problems, but a good cleaning seemed to fix any issues. But even in the beginning with 30-06 I noticed that 1 of 7 rounds would fly by the slot and not drop, the other 6 usally dropped with no issues. Not that this only happens when is aligned West to East (Meaing the base of the cartridge is on the West/Left when it passes the slot). Any cartrige aligned East to West always drops.
After cleaning the machine throughly, Ineeded to load up 400 30-06 rounds. So I got everything setup, loaded the case feeder and off I went. I fired up the case feeder and noticed that 3 out of 7 were not falling in the slot. The case plate felt greasy, so I cleaned it with some De-greaser. Tried it again and same problem. I then called Dillon and had me inspect the case plate and asked me if there were any burrs or flashing on slots that are on the plate. I did notice one or two slots had some flashing. Dillon said I should take a file and remove the flashing. I did this and tried it again. Same situation 3 of of 7 (on the average) do not fall in the slot. I called Dillon again and they had no answer. So I struggled through the 400 rounds and did nothing for about a month.
I grapped about 150 clean and readly to reload rounds and dumped them in the hopper and disconnecte the down tube and aimed it into a coffee can. I fired up the case feeder and an average of 3 out of 7 don't fall. If you touch the round when it goes by the slot, it will fall. It seemed like the brass was being held against the slot in the plate. Since I made up my mind to fix this problem, I decided to drill a small hole in the middle of the case feed plate slot. I then pressed a small piece of solder in each hole, cut it off and rounded the end of the solder over like a small rivit. I reassembled everything, dumped 150 rounds in the hopper and turned on the feeder. Guess what - Every round now falls when it approaches the slot .
Any Ideas why ?
