Well I am certainly not ready to take this thing long range then... I shot @ 200 yards today the loads 44.1, 44.2, 44.3 and 44.4 and still saw a large ES and the SD wasn't that great either. The load that grouped best had the highest ES and SD.. I didn't waste any time shooting these 20 rounds. I shot 10 let it cool for a little bit and shot the remaining 10 rounds... I took a few measurements while reloading these...

outside neck after sizing = .288
necks turned to = .014
outside neck after seating= .290
