Excellent thread really. That was a great fix for the oversized gas port.
I knew you had plenty of gas since you were getting Last Round Bolt Hold Open every time, but stovepipes and 1 o'clock ejection.
You can also tune the corners of your extractor lip and it will baby brass more, without any chance to impinge the case rims during ejection articulation from the bolt face recess.
I do that on my builds if they don't have a precision ground edge on the extractors.
Keep an eye on the chromed bolt, as that is usually a recipe for hydrogen embrittlement and stress risers at the lug roots and cam pin hole.
If fed a diet of Wolf, it should last longer though since projectiles are smaller diameter and charge weights aren't very high.
