Primer striking is affected by a bunch of things. And even while striking is sufficient/reliable to set off every primer, it can still kill grouping if at a bad setting.
Does it makes sense that primer striking would affect grouping? Not to me..
But I found that it does and I suspect optimum is not the same for every primer brand.
The pin itself(it's boltface protrusion) should be adjustable inside your bolt. This is an easy adjustment to striking. If you change triggers, take care to measure pin protrusion beforehand, especially if you've already invested in load development. With this you can reset it if performance falls apart.
With a different trigger the firing pin can pull back a bit more or less, there might be more/less drag on release. Ever notice drag at the action tang? Or bolt handle bump/turn on dry firing?
Pay attention to this stuff.
