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!
