I just finished checking the capacity of my '06 brass just out of curiosity. I checked 5 LC69 cases against 5 Lapua cases. The Lapua cases averaged 69.4 gr and the LC69 was 67.6 gr for a whopping 1.8 gr difference. Does that sound about right? I was kind of surprised at so little difference. I used distilled water and the LC69 cases were pull downs, never fired. The Lapua cases were 4x fired. After firing the GI cases I will check them again.
