jcchartboy,

Not to disagree with Randy but I have been using 209-4 for several years now, never have had any problems (with triple seven). Actually I am working on my fifth brick of them. My Wal-Mart has been able to supply with these primers all along. There may me some concern in sub-freezing weather about them being hot enough, but so far, nock on wood, they have worked for me. + no crud ring...
