Thread: Pressure sign in the single shot

Was out developing a load for the bergara the other day(unsuccessfully, turns out you need the pic rail screws to be tight to shoot good groups) when it occurred to me that I didn't actually know what to look for in pressure signs. My primary indicator has always been ejector flowi/swipes.

I assume you just have to go entirely off primer flattening and cratering? Primary extraction is pretty strong due to the massive lever so hard to detect hard extraction. Anything obvious I am missing?

Load were 168 nbts over H335 in winny brass. 42.5 shows some flattening and a minor crator. This sound abiut right?
