I am new to reloading and have been working on some rounds and then checking them on a Caldwell Chronograph. My SD Is really bad. I am loading 6-10 rounds and measuring my powder with a Franklin digital scale. I do not ensure all of my case lengths are the same but they are all in spec. I am hoping someone can tell me what to tweak so I can get consistent rounds. These are not for competition jut range shooting. Here is what I have:
9mm (SD 23.2-24.4)
Federal case (once fired)
Copper plated 115gr
Titegroup 4.2gr
CCI SPP
COL vary from 1.153 up to 1.16
.380 (SD 36.7)
PMC Case (once fired)
90gr XTP
Titegroup 3.2
CCI SPP
COL .964-.9655
Thanks for sharing your expertise
