Now I'm thinking that a super hard strike on the primer might be moving the case in the chamber slightly, and also have a nagging feeling that the firing pin might hitting so hard that it's bouncing on the primer face. Perhaps I'm wrong, I don't know. But the subject makes me think a little bit
Lock time can be improved in several ways. Heaver springs or lighter firing pin assemblies.
Most of the speed locks kits have both but with the lighter firing pin the inertia is reduced
some and if set properly should not cause piercing.
As far as pushing the case forward, they all do that and head space has control of how much.
The coiling effect of the Factory spring producing drag on the bolt body Is the main problem
with lock time in factory rifles.
I don't recommend a spring or firing pin assembly change just to do it. Only if there is a problem.
With good shooting skills (Squeeze and follow up) lock time is not that important unless it is
very slow, then it can help.
Also as some people have found out, the proper installation is paramount for good performance
of the firing pin assembly.
Firing pin protrusion must be set correctly to have good performance.
You are right to think about it because in many cases it is not nessary .
Whats the old saying "If it ain't broke,Don't fix it".
