...I've been having some problems with loading my .357 Magnum cases rather full on my Hornady LNL AP and small bits of powder being shaken out of the case when the shell plate makes its sudden stop in the indexing holes. These granules eventually make their way into the primer shuttle area causing *^%#@%$#&!! misfeeds. Has anybody else had this issue, and if so, found a solution?

I've tried ultra-fine tuning of the indexing pawls, dabs of grease in the indexing holes (which simply gets squeezed out), to no avail. It seems this case "rattling" is inherent in the indexing design.

Since I bell the case via PowderFunnel in my powder measure and also seat and crimp in one operation with this caliber, I'm going to move the powder measure from station two to station three and use my finger(s) to neutralize the case rattling until I can figure out a better solution.

For what it's worth, I'm loading 17.0 grains of 2400 behind a 125-grain JHP. No doubt I would have even more problems with rattling cases and powder flinging if I were doing the same with 21.2 grains of H110 in this scenario! (I previously loaded said charges in modified single-stage mode and may begrudgingly revert to it).

Any and all suggestions would be greatly appreciated. Thank you in advance.
