Master Blaster and loadedround nailed it, bullet seating stems and replacement decapping pins for Dillon dies. Thanks, guys, on my own, may never have figured it out.
This is turning out to be a good buy, a Dillon 550B, 10 complete caliber die sets, a bunch of powder and primers, books and manuals, a ton of 9mm, .38, and .30 cal brass and bullets. Think I'll order the Dillon video and peruse the reloading manuals.
Again, thanks,
Ken c
