Question about pressure

[The_Whitetail_Kid]

In my CA Ridgeline 6.5 PRC I am having slight pressure (faint ejector marks), no sticky bolt lift, with 57 grains h1000, cci250, ADG brass, 156 Berger. I am seated 2.950, 55 thousands of lands (this is because Christensens have a short chamber). I have tried backing off the powder half a grain, while the group is good, it is not as good. Should I try making my bullet 5-10 thousands longer, I measured that and know I can get away with it, or should I back off .2 or .3 grains of powder and try that?

Christensen rifles have double ejectors with heavy springs so that's very common. I would not worry unless you are seeing other pressure signs or are over book maximum loads.

^^^ this. Faint ejector marks aren't a pressure sign in Christensen rifles usually. Sticky bolt is.

What is your velocity? Velocity is your pressure sign
