Thread: Over pressure signs ??

Tim

Both primers look ok to me.

I don't see any obvious signs of over pressure that would concern me at this stage.

Primer on the left still has a visible radius and no sign of cratering around the firing pin strike.

Was there any other signs of over pressure, like sticky bolt on opening or difficulty extracting the case from the chamber?

I'll post some pics later with examples of flattened and cratered primers that while up in pressure were not causing problems otherwise.

The darkened ring around your firing pin hole on the bolt face may be due to a loose primer leaking rather than over pressure.

Cheers
Pete
