[QUOTE="Deleted member 46119, post: 1295174"] I forgot something that I think @Mikecr and I disagreed on before but we may be closer now. The "shape" of the inside of the case like how thick the base is or how thick the walls are. Previously I believed that this did not have any effect. I was right and wrong at the same time. I was right that it does not effect volume if the outside of the case is well fire formed. Where I was wrong is that the share and where brass is thick or thin effects how the gasses expand. Quality brass will be more consistent on it's internal shapes like wall thickness and base thickness. So it will "shoot" better. Lapua and Norma are more dimensionaly consistent. The bummer is that to measure this AFAIK you have to destroy the case. [/QUOTE]
