Lee warns against using Federal primers in their hand primer tool. They say (talked to them on the phone) they worry that there may be a chain detonation with the primers, and you could get injured. Are Federal primers that much more sensitive to handloading and care than the others? They suggested in a pinch, one primer at a time, and to wear safety glasses, and protection. Anyone else out there use Federal primers with LEE or other brands of hand priming tools? Are they really that more sensitive?
