The lifetime warranty RCBS has on their products is outstanding.
I have a bench mounted Auto Prime tool from the 1970's that has seen untold thousands of cycles over the decades. The large primer stem wore to the point it would not reliably go up and down and pick up primers from the tube any more. For the last few years I have assisted its operation with my finger to make it work and recently that did not even work.
It is funny how we just limp along with something that needs help or repair.
I looked on ebay for replacement parts and few were found - none new. The light came on in my head and I called RCBS. The very nice customer services woman quickly identified my needs and sent the parts to rebuild my primer tool. FREE!
After all these years I would have been happy to pay for the parts, or if none were available just buy a new tool - my old primer tool owed me nothing after all it has done.
Two thumbs up for RCBS.
