I am glad you reminded me of the book stating that, I forgot that I read that in the manual.I was recently using Federal primers in the lee hand primer. (without incident) I can imagine that could put a racin stripe in the shorts when you are not expecting it.

Probably would not be a bad idea for Lee to print it right on the top of the primer tray lid. Just for us guys that dont ever look at the instructions untill after we figure out how it works.
