Thread: What's going on here??

Like 7mmsaum alluded to, some chronies will give varying results depending on whether its clear skies or overcast. Assuming his reloading process was good to go and the data shown was all for same charge weight then I'd validate at range using an MV of around 2480fps (close enough to the average of first group which from the data is what I'd interpret as the most reliable). Sing out if you want me to send you data for what your drop should be at desired range. Cheers
