High Pressure = Hard Extraction

Could this also be due to a poorly tuned gas system unlocking too early under higher than designed pressure, in the absence of other pressure signs?

Pressure needs to drop, allowing brass to spring back before extraction begins, to avoid rim damage.

The case body is showing high pressure. Would look same in a bolt action. No spring back of the brass is a sign. Hard extraction.

Got it, only reason I asked is because I have seen factory loads look similar to this due to carbine gas system over gassing due to gas port being too large and unlocking too early but no ejector extrusion or swipe primer nice and round. Case looked rough and rim was bent with extractor claw marks under it because of the over gassing. with the case still under higher pressure it was still pressed tight in the chamber. Adjustable gas block “fixed” the issue. Only reason I brought it up was because until the over gassing situation was taken care of the brass looked very similar to this photo.
