Thread: Pierced ginex primers

Had a surprise when I looked at some brass from a recent shoot. These were all loaded in virgin lapua brass with 25.7gr of 8208 behind a 130gr sierra game changer in a howa mini grendel.
This was a load that seemed to be fine previously, not running too hot according to the chrono and no heavy bolt lift when shooting these. Still knocked over the goats and possums just fine.
Not sure if these ginex primers are thin and blowing too easily, or if my powder scale (FA intellidropper) is inaccurate and throwing a few more spicy loads.
Has anyone else found the ginex small rifle primers are causing issues?
