About a year ago I read an article about primers, rating the the cup hardness and the power of the different brands of primers. I can't remember where I read the article. I've went back through my magizines and can't find it. I'm looking for the rating that lists the primers brands and numbers from the softest to the hardest ignition. Please let me know if you can remember what magizine this article is in, I should have the magizine. I've also seen this chart in other places, in the past, I just can't remember where. Any help is appreciated.
