Can someone school me on why when developing a load, the SD is crap for maybe the first 4-5 loads, and then BAM, single digit.
For example:
22 grns 18.9
22.5 grns 21.2
23.0 grns 15.4
23.5 grns 22.6
24.0 grns 7.0
These are 5 shot groups, and I read the the posting on number of shots required to have confidence in the actual numbers. Everything being the same except charge weights, what makes the numbers come down? Or is it just an anomaly that I need to shoot more shots?
Thanks
