A few months ago I decided to load some .300 win mags. I primed them then something came up (can't recall what it was ) and never got around to loading them. Now I'm looking to finish them but I'm a little worried about the primers. I doubt there is anything wrong with them but I'm a worrier and just envision pulling the trigger on a bull of a lifetime and hearing "click". they have been on a shelf literally right next to where I keep my primers. Just not in the packaging. What do you guys think? Am I worrying about nothing or do you think I shouldn't trust those primers?
