I ordered the case feed the other day for my 550b and after setting it up and reading the instructions twice I started on the installation. Got everything set up for production so I thought, the cases seem to not go fully into the shell holder so the case sometimes doesn't line up with the die unless i push the case fully in with my finger, this also causes the primer seater to not line up perfectly with the case primer pocket. After talking with the nice folks at Dillon and and the trouble shooting section in the instructions I adjusted the roller bracket until the indexing arm was hitting the cam bracket and backed the adjustment off somewhat but the cases still are not fully seating. I feel like the problem is me and not the equipment. I did use an empty tool head with a powder die in station one with the alignment tool in it and made sure the small diameter end went into the primer pocket but doesn't seem to go all the way into it and this maybe part of my problem. However the two bolts that holds the platform to the ram doesn't seem to have that much adjustment. If anyone has ran into this problem setting up the case feed I certainly would appreciate some advice.
