[QUOTE="BrentM, post: 869349, member: 61747"] I prersonally believe this accuracy variance is the combination of pressure and depth. Perhaps that is what you are eluding to. I have played around with depths for a long time and did not see much change in spread via seating depth with a few thousands between loads. I do see issues with brass flex and neck tension and that is usually quite evident on the chrono. If the pressure spikes due to a tight neck or inflexible brass you could easly see a 50 fps jump. That is about like adding a full grain of powder to your case. [/QUOTE]
