Bunch of things that can go wrong with striking.
With an empty chamber, watch the bolt handle on dry firing. If it rotates at all, it took away from striking energy to do that. Trigger position and sear drag increases lock time and reduces striking energy. Firing pin fall distance, it's weight, and then all the attributes of springs affects striking energy.
My reference to striking energy includes striking SPEED.
It is unfortunate above all that we lack any striking standard.
We have no measure or calibration process for striking.
And one thing I've learned, but am unable to define without a baseline standard, is that merely setting off every primer is a horrible standard. It's not good enough.
If you adjust released firing pin protrusion with group testing, low to high, you may see that while every single primer fires, grouping still goes from open to close & back to open. I did this. That's what I saw, and I gained a great deal from it(results-wise).
It's a long story, but I believe this could be done in lieu of abstract primer swap testing. That it's possible any primer could work as well as any other, with striking calibrated for it.
