Re: Pressure with Neck-Sized Brass but not Full Length Sized Brass?
Put up a pic of the ejector mark. I'm wondering if it's just a shiny spot or if you have some brass extruded into the ejector hole. I it's the latter I'd say your loads are pretty hot for your gun. If the former then you'd be getting a press fit when you chamber a round. How is your extraction? resistance on the bolt lift, hard, no resistance?
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
