What were the pressures of the non 700-x loads, were they real low like 6 or 5K? I don't believe it's the 700-x making the difference, it's because it's a higher pressure than what you had been shooting.

I don't think chamber pressure is static, pressure measurements are taking at something close to room temperature. A shell that works fine in the summer and does not in the winter is I suspect producing a lower pressure in the cold temps. What is published as a 10K load is probably lower in single digits temperatures. I wonder if there are tests done to confirm this.
