Ok,
So, I went ahead and installed a 3/16th steel plate under the machine which really did lessen the movement, plus I also installed a wire tether from the case feeder to a bracket on the wall behind the machine. No movement now.
BUT, even after going through all the motions I am still either crushing a primer or getting "no" primer about one per hundred. Getting no primer is not a big deal except it gets powder in the indexing ball which really screws things up.
Talked to a supervisor at Dillon. He immediately told me to clean my machine, which I told him I had done and he went on to tell me exactly how to clean it. Thanks, I said, I know how to clean it and that's not the problem. He then told me that everyone is putting out bad primers and said I needed to use Remmington primers. I said if I had to use ONLY Remmington primers, or a certian kind of brass, I might as well send the machine back now. He said he would send me some replacement parts - end of conversation.
I am sure he was trying to help me. I am equally sure he was going down a check list of sorts in order to diagnose the problem. I plan on calling back on Monday. I hope someone can hit on something that will eliminate the problem here.
