Also, do the Dillon dies come with a carbide expander ball? If not you may need some way to lube the inside of the necks to cut down on the chattering. When I saw where you needed to lube even the Dillon carbide dies, I went another route and got a set of RCBS of Small Base dies and bought a Hornady/Pacific carbide expander for about $32 and a couple bottles of Dillon spray lube. I would guess the standard dies would show wear sooner than the real carbide dies, but I've not noticed any yet and have loaded several thousand. Make sure your brass is clean before sizing to reduce the chance of imbedded dirt scratching your brass.
On another note, did your grandson bring you commercial brass or crimped primer military? If military you'll need to clean up the primer pockets before repriming. There are a couple ways to do this. Hopefully you have commercial.
