Update:
On a whim, I called the number above and got Sharon, live. I gave her the lot numbers I had on hand and she is sending out packaging for returning them. I've got to say that I'm impressed with her and with the company's response. Stuff happens; what matters is how it's handled. This is much better than Plan B.
+1.
I left a message for Sharon who called me back within a day. I gave her the lot # of the WLR primers (GML424G; quantity of 1,000). She asked if I had experienced any problems and I told her that I had not used them yet. She indicated that, though there were no reported issues with this Lot # of WLRs, she would be sending a package in which I could return them just to be sure. I also gave her Lot #s for WSP & WSPM primers I had on-hand but those are apparently ok, since she she did not indicate a need to return these. Sharon was very pleasant and responsive.
