Finding dents on my ejected case main body (my Satern Spartan home build, see first picture). I don't get this dent on my AA built Entry upper. The middle picture shows lack of denting on neck with my home build, while the third picture is the dented neck from AA Entry.
What would cause the dented main body? Will this affect reloading safety?
I am running a PRI adjustable gas block and have tuned the gas return down significantly to avoid the dented neck and increase velocity. The action cycles just fine (locks open on last round with no failure to eject/feed). I started at fully closed, then 1.5 turns open. From there I closed it another half turn (now 1 turn from fully closed). Dents occur at both settings.
Is this possibly not enough gas to cycle carrier in time for case to clear the ejection port before being slammed to the side? The dented cases end up at the 2-3 o'clock position at half the distance of the fully gassed AA Entry (Entry brass ends up at the 4 o'clock position).
