Hello all. Before I get started, yes, I've searched the ends did the internet looking for a comprehensive answer to this question.
I was bit by the reloading bug several years ago when I was stationed in Rapid City. Elevation there is about 3300 feet. About a year ago I was re-assigned to NW Louisiana, where the elevation is about 300 feet.
Not once did I ever experience case over pressure while in Rapid City. No case flow, no sticky bolt, no cratered or flat primers, and no popped primers. As soon as I moved down here I've had it in three guns. The only, but undeniable, sign is a perfect circle from case flow into the plunger. My Savage 30-06 (the worst offender) and my 22-250 and 7mm-08 in 700s all seem to b sensitive to it now. New brass to boot.
The only variable that has changed is altitude and to a degree humidity. I'm shooting my same supply of powder that I had up there in very similar temperatures. Can someone please teach me the science as to how a slight change in the mercury can cause this, or give me a second opinion to the cause?
