This changed my rifle to the good! - JP Enterprises .224 Valkyrie Enhanced Bolt Assembly

I installed this on a 400 Legend I built. I handload my ammo, and this allows me to progress to the upper end of my pressure range without primer extrusion. Although my load was not close to maximum, i was getting primer extrusion around the firing pin indent. After this upgrade i am cruising 1/2 a grain under maximum with no primer extrusion at all. There never was any over pressure signs other than primer extrusion.
