If you have a Faxon FX7 chambered in 8.6 Blackout, do not order ammo from us. The primers we use may not ignite in your FX7 which may result in light primer strikes. We’re not sure if it’s a design flaw on the manufacturer’s end or that the primers we use are harder than standard primers, but we’ve used several different brands of primers in the FX7 resulting in unreliable detonation.
