I recently picked one up and got it set up on the bench so that it is level both left to right and front to back. I have the screw that secures the plastic feeder set so the feeder floats, I have adjusted the rheostat control and I am still getting a few primers (4-5/100) that hang up sideways going into the tube. Any of you guys have any experience with the RF-100 and have some tips to share? Thanks.
