I ran two 10-shot strings of the same load over my chronograph today. I'm at about 960 feet elevation and it was a calm, 40 degree day. Unsuppressed I only averaged around 2410 fps out of my 18" Lilja 319 barrel. MY ES spread was very tight on one string and opened up to around 43 fps on the other thanks to two rounds that were down around 2370-2375 fps. I didn't have a lot of time, so I didn't take my can with me and I didn't shoot groups. I just shot steel at 400 yards to get some chrono data. I think I'm going to run some of my ammo back through a Lee FCD and compare them with loads not crimped. I'm thinking maybe the FCD will improve my consistency and lower my ES.
