    I've always had trouble with my powder-through-expander crunching the side of a few shells (I load .357 Mag.) -- sometimes one per hundred, sometimes more. The nylon tip on my RCBC powder lockout die was also randomly catching on the side of a shell here and there. This slowed me down a lot, because I had to visually check every case as it went over the PTX.

    I tried adjusting the timing, chamfered and polished the PTX, called Hornady (they said they'd never heard of that problem) and generally messed around trying to find a solution. I finally decided that the case didn't seem to be held very tightly against the subplate by the shellholder -- most cases would rock back and forth a bit, so I took a chance and ordered another shellplate. I just received it after a long wait, and it totally solved the problem. Now the empties are a much tighter fit, and barely move. They're aligned much better with the PTX, and I don't think they'll ever get caught.

    I haven't measured the difference in depth of the lip that holds the shell's rim, but it's not visually obvious -- I don't think it's more than a few thousandths. In any case, it's enough to hold the shell much more tightly, and it solved a problem that's been nagging at me since I bought the press last Fall.

    Maybe this will help someone else out -- I have no idea how widespread this is.

    Thanks for the tip. I have had ocassional problems with cases hitting the sided of the dies and have crushed a couple out of the 1200 or so I've loaded. I had noticed that the cases were "loose" fitting. My problem seemed to get better after replacing the spring. If it happens again, I will see if it is only happening with a particular shell plate.
    I hope you let Hornady know this solution. They will likely reimburse you for the plate and keep this in mind if others have the same problem.
    Thanks for sharing!!!

    Hornady folks are great service reps...
    Maybe offer to send them that one in exchange for a different numbered plate that you need anyway.

    I have not used that plate yet but it is on order.
    What were your measurements?

    As a SOP: Eyeball for burrs, file as needed. I have been polishing mine and friends on a large diameter, narrow pad buffering wheel, using compound. Less drag = smoother operation = SPEED
