I bought my RL550b in October of 1991 -- God knows how many times I operated the handle. Well, today I had perhaps my 2nd or 3rd failure in 27 years -- apparently the cast aluminum piece which hold the roller the powder measure gets actuated by broke off! While contemplating cutting some tin-can stock as a piece for the front and back; joining with super-glue or epoxy, and finishing with a couple of brass pins, I said, "what the heck?" and rang their 800 number. I got a genuinely pleasant chap, who chuckled that the three digit part number I offered has been "long ago" replaced with a 5-digit one, and he will put a new sheet with current numbers, AND A KIT INCLUDING MY PART WHICH BROKE -- in the mail to me tomorrow. NO CHARGE!
I've oft' heard of their "No B.S. Warranty", but never needed to use it. I had purchased their spare parts kit when that silly shell-plate ball rolled into never-land, maybe 25 years ago as my only parts need. (It's still missing)
In this day of most questionable business practices by ever so many, Dillon has, in my book, joined RCBS as being in the #1 category!
