I have put together a F-Class Model 12 from used parts
Target short action
Factory Savage 6mm BR barrel
New Lapua case
Accu-Trigger and yes I fully understand the slamming the bolt safety feature.

Now it will fire an empty primed case but will not fire a loader round. Not just one time.

No mark on the primer and the sound it makes is just like you would expect, just like pulling the trigger on an empty chamber.

I have taken the bolt apart and inspected it. I see nothing wrong with it.

Bolt closes snug, maybe on the tight side of snug, on both cases.
