What year did problems with Winchester primers seem to surface? All my WLR's are marked with a sharpie purchased from the 2005-2007 year range. (have a good supply)

They are all I use to load the LeverEvolution rounds for our nine 30-30 rifles.

I did once see a partial lot number list but was wondering what approximate years they were produced?
