I've been using NSI 688 with perfect satisfaction. 10,000 primers fired so far, zero misfires. I have found 3 in the primer feed tray that did not have the green cover on the flash hole, so those were not used.

They do not pierce in my Brownings like Cheddites do, and they reliably light ball powders unlike Fiocchi 616.

My last 10K carton was $459 from a vendor at the state shoot.

I hope Winchester goes broke.
